These two words have come to symbolize the unmitigated horror brought about by the terribly destructive power of atomic weapons. If war represents the failure of diplomacy, then modern thinking would dictate that the use of nuclear weapons is the ultimate failure of diplomacy. However, when viewed during World War II through the eyes of American and British military and political leaders who had shown little moral anguish over the firebombing of German and Japanese cities, the question of whether to use the atomic bombs was never really an ethical issue. Seen as "just bigger bombs", there was little doubt that the atomic weapons would be used against either Germany or Japan if they became available during the war. With the surrender of Germany in May 1945, Japan was targeted for the bombs which were expected to be ready within months. At the same time, there was also a growing realization among these same leaders that the future adversary of the United States and Great Britain would be their "Grand Alliance" ally, the Soviet Union. Unknown to newly sworn President Harry Truman, Franklin Roosevelt and British Prime Minister Winston Churchill had developed an agenda that was significantly broader than merely bringing an expeditious end to the war with Japan.' Use of the atomic bombs would consummate their secret grand strategy for shaping the political landscape of the postwar world. In their vision of the "new world order" of that era, the atomic bomb would serve as the diplomatic hammer to ' As documented in detail by Martin Sherwin in his book A World.Destroyed, this agenda was formulated in conjunction with the signing of the Quebec Agreement in August 1943. Further discussion is provided on pages 7-8 of this paper. ensure that Anglo-American global political objectives would not be seriously challenged by Joseph Stalin's desire for hegemony over Eastern Europe and the Far East. While Roosevelt had never taken his new Vice President into his confidence, Truman would soonlearn about the existence of the atomic bomb and its potential use as a coercive diplomatic tool from his aged Secretary of War, Henry L. Stimson. As Stalin continued to renege on agreements made at the Yalta Conference in February 1945, the new American president began to understand his predecessor's concerns about dealing with the recalcitrant Soviet dictator. By the time Truman sailed for the Potsdam Conference in July 1945, he had essentially made up his mind to use the atomic bombs (assuming that the upcoming ground test at Alamogordo, New Mexico proved successful) first priority was to compel the Japanese to surrender least cost of American lives. He considered to end the war. His unconditionally at the a full-scale invasion of the Japanese homeland as an undesirable contingency to be employed only if the atomic bombs were not viable weapons. Concerned that the American people would not accept anything less than unconditional surrender from the perpetrators of the sneak attack on Pearl Harbor, he rejected the idea of providing the Japanese hierarchy assurances that Emperor Hirohito could be retained. mindful of the Churchill/Roosevelt designs under control. attitude over Truman was also strategy for keeping Stalin's expansionist He was already concerned with Stalin's the administration of Eastern Europe, especially belligerent Poland. The President must have realized that despite his best efforts, Soviet domination of Eastern Europe would be difficult to prevent. war expected recognized to take the need to place within terminate potential foothold in the Far East. the Thus, with Soviet entry into the first two weeks the war before of August, Stalin could gain Truman another In my estimation, Conference. Truman made two serious mistakes while at the Potsdam Almost fifty years later, the world still suffers for his failure to employ better diplomacy towards our Soviet ally and our Japanese enemy. I believe that Truman should have told Stalin of the bomb's existence at the Potsdam Conference after he learned that it had been successfully tested and before it was actually used. He would have sacrificed little, since the potential diplomatic value of the bomb was predicated on its actual use during the war. weeks. Indeed, Truman was already set on a course to use the bombs within two If Stalin already knew about the bomb (which, in fact, he did), Truman had nothing to lose. If Stalin was ignorant of its existence, then it was unlikely that merely finding out would jeopardize any strategic advantage already enjoyed by the United States and Great Britain. In either case, Truman could have demonstrated good will towards the Soviet dictator in hopes that it would be reciprocated. Instead, he was extremely coy with Stalin. Keeping the existence of the bomb an Anglo-Amerlcan secret perpetuated the paranoiac Stalin's worst suspicions of his Grand Alliance partners and was arguably responsible for precipitating the Cold War and the nuclear arms race. It is also my opinion that Truman made an egregious error in judgement when he decided not to rescind his demand for the Japanese to surrender unconditionally. The Potsdam Declaration was the culmination of a seriously flawed diplomatic strategy. ~ad Truman attempted to negotiate the continuance of the Imperial System with Japanese leaders, the end of the war might have been accomplished before the Soviets had the opportunity to have any significant impact in the Far East and without the use of atomic weapons. I will offer my own blueprint for how this might have been done in the section entitled "In Retrospect: Should We Have Used the Atomic Bombs?" The First Nuclear Arms Race: Buildinq the Atomic Bomb From Science Fiction to Reality The genesis of the first nuclear arms race was a science fiction novel written in 1913 by H.G. Wells. Set in 1956, The World Set Free describes how a global nuclear war using "atomic bombs" destroys 200 of the world's cities, leading to the establishment of a world government. ~ Twenty years later, Hungarian-born physicist Leo Szilard whimsically recalled Wells' idea as he imagined how the process of transmuting one element into another could simultaneously generate a vast amount of nuclear energy. Szilard theorized A recent emigre' to London from Nazi Germany, that such an atomic bombardment of an element by neutrons. reaction could be effectuated through He shared his theory with a small group of colleagues in the scientific community, hoping that this special element could be identified through laboratory experimentation. It was not until late 1938 that German physicists Otto Hahn and Fritz Strassmann discovered that uranium, the heaviest transmuted into barium when subjected of the 92 elements to neutron then bombardment. known, The atomic reaction also generated radioactive elements as an unexpected by-product. wrote to a former colleague, Lise Meitner, interpreting the results of his experiments. asking for her was assistance Hahn in She and her nephew, Otto Frisch, an experimental physicist at the Neils Bohr Institute for Theoretical Physics in Copenhagen, confirmed that nuclear fission had, in fact, occurred.' 1939, the first of several papers was published informing In January the rest scientific world that nuclear fission was indeed a new verity. of the Using Albert Einstein's famous equation, E = mc z, scientists calculated that fissioning of just one pound of uranium would release as much energy as 8,000 short tons of TNT. a The successful splitting of the uranium atom had made H.G. Wells' vision published on the eve of the First World War a potential reality - the actualization of which would prove to be decisive in ending the Second World War and fomenting the start of the Cold War. Race to Beat Germany Szilard and his tightly-knit group of fellow physicists, now located in the United States, soon surmised that Hitler's Germany had the wherewithal to develop an atomic bomb. In addition to possessing the scientific knowledge to begin research, Germany could gain access to the world's largest reserves of high-grade uranium ore from the Belgian Congo. Szilard and members of his "association" decided that the United States must win the race to build the first atomic bomb. In the spring of 1939, Enrico Fermi unsuccessfully tried to interest the U.S. Navy in performing atomic research (Navy officials were ignorant of Fermi's scientific credentials and suspicious of the motives of the Italian emigre'). ~ In July, Szilard enlisted the help of Princeton physicist Eugene Wigner in visiting the eminent Professor Einstein. Szilard had hoped that Einstein, who knew the Belgian queen, would sign a letter warning her of the danger of German seizure of the Congo's uranium reserves. Einstein signed the letter and it was agreed that a copy would be sent to the U.S. State Department. Later, Szilard had that second thoughts about sending the letter and decided approaching President Roosevelt was the preferable tactic. wrote another letter for Einsteln's signature. directly In August, Szilard It was delivered to the president by Alexander Sachs (a Russian emigre' with access to the White House) in October, six weeks after the outbreak of war in Europe. After reading this now famous letter, Roosevelt told his personal aide, General "Pa" Watson: "This requires action. ''~ Soon thereafter an ad hoc Uranium Committee was formed to study the possible military applications of recent discoveries in nuclear fission. With the creation of the National Defense Research Committee (NDRC) in June 1940, atomic research began to acquire its own impetus. Under chairman Vannevar Bush, the purpose of the NDRC was to seek new opportunities to exploit science for the prosecution of the war. While atomic research would have to compete with other weapons research for funding, the means to investigate the feasibility of the atomic bomb was now established. ~ A year later, in June 1941, Bush created the Office of Scientific Research and Development (OSRD), an umbrella organization under which the NDRC would operate. James Conant was named the new chairman of the NDRC. reported directly to Roosevelt. Under this guise, Bush In July, he advised the president that if it were technically feasible to develop the atomic bomb, use of the weapon might have a decisive effect not only on the war, but in shaping the future peace as well. In January 1942, a month after the Japanese attack on Pearl Harbor, Roosevelt gave Bush the go-ahead to proceed with developing the atomic bomb. ~ The Nanhattan ProTect The Manhattan Project was born in March scientists was put under Army direction. 1942 when the work of the atomic Brigadier General Leslie Groves was selected to head the project, and his official appointment came on 17 September. Groves was directed to coordinate his activities with Conant at the NDRC. two days later, as Fermi and Szilard continued their experiments at Just the University of Chicago, the site for the uranium separation plant was acquired in Oak Ridge, Tennessee. In December, Robert Oppenheimer was appointed director of the newly constructed bomb laboratory at Los Alamos, New ~exico. j Meanwhile, on 2 December the watershed event in the development of the bomb took place. the Under Fermi's leadership, the University of Chicago scientists produced first self-sustaining chain reaction in history. This landmark accomplishment effectively demonstrated the feasibility of the atomic bomb and ended the basic research phase of the project.' Bush advised the president that the first atomic bombs would likely be ready for use in early 1944. I° Bolstered by proof that atomic bombs could eventually be produced i, Franklin Roosevelt turned his attention to formulating a new grand strategy to meet the wartime and postwar objectives that had been alluded to by Vannevar Bush some 18 months earlier in July 1941. Use of the Atomic Bomb: The Rationale is Developed Atomic Monopoly I: The Seed is Planted Since the summer of 1940, the United States and Great Britain had agreed to share secret technical information to be used for the conduct of the war. While the British specialized in radar systems and codebreaking techniques, the Americans performed the vast majority of the research and development of the atomic bomb. Bush and Conant strongly pursued the open exchange with the British until the breakthrough on 2 December 1942. Enlisting Secretary of War Henry L. Stimson as an ally, they now advised the president that there was "no reason for a joint enterprise as far as development and manufacture (of the atomic bomb) is concerned. ''Lt As expected, the British objected vehemently to this change in the relationship with their American counterparts. Discussions culminated with the signing of the Quebec Agreement on 19 August 1943 by President Roosevelt and Prime Minister Churchill. With this pact, the bases for Anglo-American i Solving the remaining technical problems fabricating, and testing of a working bomb would take until July 1945 at a total project cost of some S2.5 billion. (Cardinal Choices: 15) cooperation on atomic energy policy as well as general diplomatic and military matters relating to the atomic bomb were established. In particular, Roosevelt tacitly endorsed Churchill's view that Anglo-American control of the atomic bomb and the means of its production should be used as a powerful coercive instrument to thwart Soviet hegemony in Europe following the winning of the war. u The seed was now planted for an Anglo-American atomic monopoly. but "two policemen" to rule the postwar world. There would be As Churchill had hoped, the development of the atomic bomb would be kept secret from the French he despised and the Soviets he feared. Atomic MonoDolv II: The Die is Cast A month following the signing of the Quebec Agreement, the world-renowned physicist Neils Bohr escaped to England from Nazi-occupied Denmark. Once he learned of the Manhattan Project, he embarked on an effort to encourage American and British diplomats to adopt an atomic policy that could be used to shape postwar relations with the Soviet Union. Bohr argued that the Soviets should be informed of the existence of the Manhattan Project, but that they should not be provided any technical details until such time as they guaranteed "common safety against the unprecedented dangers." He further argued that only by promptly inviting Soviet participation in postwar atomic energy planning (before the bomb was a certainty and before the war was over) could mutual mistrust between the Anglo-Americans and their Soviet allies be avoided. In Bohr's view, failure to bring atomic energy planning under international control would inevitably lead to a dangerous nuclear arms race. ts On 16 May 1944, Bohr was finally granted an audience with the British Prime Minister. Preoccupied with planning the invasion of Europe scheduled for the first week in June, Churchill impatiently greeted the famous scientist and allowed him little time to present his ideas. He terminated the short meeting by making it clear to his visitor that he did not want to hear any more of his political opinions anytime in the future. Not a man to be derailed easily, Bohr continued to press for acceptance of his views. of On 26 August, Bohr met with Franklin Roosevelt. the Normandy invasion, the president cheerfully presentation and even indicated that he agreed in concept. Elated by the success listened to Bohr's He told Bohr that the details would be worked out when he met with Churchill the following month. On 18 September, the meeting was held at Roosevelt's estate in Hyde Park, New York. The outcome was an aidelemoire rejecting Bohr's ideas for international control of atomic energy. Further, in light of the optimism about the end of the war in Europe, the potential target of the atomic bomb was changed from the Germans to the Japanese. However, the memorandum cast doubt, for the first time, on whether the bomb would be used in the war at all. t~ The matter should continue to be regarded as of the utmost secrecy; but when a 'bomb' is finallyavailable, it might perhaps, after mature consideration, be used against the Japanese, who should be warned that this bombardment will be repeated until they surrender, ts In addition, the die was now firmly cast for extension of the Anglo-American atomic monopoly for an indefinite period after the end of the war. Full collaboration between the United States and the British Government in developing Tube Alloys for military and commercial purposes should continue after the defeat of Japan unless and until terminated by joint agreement. ~* Thus the Quebec Agreement was reaffirmed. As history would prove, Neils Bohr's worst fears of a dangerous postwar nuclear arms race would become the reality of the Cold War. 9 Yalta: Prelude to Atomic Diplomacy: As the defeat of Germany became inevitable during the autumn and winter of 1944, tensions between the Grand Alliance partners were heightened. Churchill sought the expeditious termination of the European war as British manpower and financial resources dwindled to critically low levels. He realized that attainment of that objective mainly hinged upon the continued-4uccess of the powerful Soviet army now moving westward towards Germany. At the same time, Roosevelt was most anxious for Soviet intervention against the Japanese, especially in light of the recent failures of Chiang Kai-shek's Nationalist forces on the Chinese mainland. The shrewd Marshal Stalin astutely recognized how deeply his two allies depended on his cooperation in achieving their own strategic goals. As the end of 1944 approached, Stalin understood that he was in a uniquely advantageous position of strength in demanding political and territorial concessions in the Baltic States, the Balkans, and most of Eastern Europe. With the Yalta Conference scheduled for February 1945 fast approaching, the Big Three and their respective diplomatic operatives struggled to reach mutual agreement in five areas of policy: 1. The treatment of Germany; 2. The future of Eastern Europe; 3. The restoration of colonial empires; 4. The nature of the international security organization to be established; 5. The nature of postwar diplomacy. c The material for this section was primarily drawn from The Semblance of Peace, pages 188-213. 10 With respect to the treatment of Germany, the~e was general consensus that Germany would be demilitarized and that some sort of joint occupation would be required for some indefinite future. The major issues to be resolved mostly related to how the process would be implemented. Pre-conference discussions of the political-and territorial interests of Great Britain and the Soviet Union soon became paramount. Much to the displeasure of President Roosevelt, Churchill had already made inroads with Stalin over the connected issues of Eastern Europe and the Balkans. greatly feared The British Prime Minister that the loss of Greece to communism could domination over Mediterranean countries such as Italy. lead to Soviet While continuing to show resistance to Stalin's plans to subjugate Poland, Churchill offered to allow Stalin to take the lead in determining the political fate of Bulgaria and Rumania in exchaage for the Soviet dictator's assurances that the issue of Greece would be left to the British. Further, the Soviet Union would be given a 50% share of the responsibility for the control 9f Hungary and Yugoslavia, with the AngloAmericans retaining the other half. I~ Meanwhile, Roosevelt was receiving mixed advice from his own foreign policy team. Secretary of State Cordell Hull and his Deputy Director for European Affairs, John D. Hickerson, argued that Soviet absorption of the Baltic States domination of Eastern Europe was almost a £ait accompli. and Instead of trying to forestall the inevitable, they advised the president to make the best of the likely new alignment in Europe. They urged Roosevelt to ensure that any political settlement made with the Soviets safeguarded the commercial interests of the United States In Eastern Europe. In addition, they further suggested that the president afford no special accommodations to the Soviets until guarantees were provided on the subjects of free elections and peacekeeping through a world 11 organization for maintenance of international peace and security. Strongly opposed to these views was Roosevelt's personal Chief of Staff, Admiral William D. Leahy, who argued that the United States should maintain an isolationist posture that would have the French, British, and Soviets work out their own agendas for settling Europe's political boundaries. It was in this atmosphere of conflicting allied concerns that the Yalta Conference took place from 4 February to ii February. d As to be expected given Stalin's position of strength, the Soviet Union's objectives were the driving force during many of the discussions. The major outcomes of the conference were as follows: i. A "United Nations" conference would be held in San Francisco in April 1945 to establish the charter for a world organization for the maintenance of international peace and security; 2. Germany would be completely disarmed, demilitarized, and dismembered with the details to be worked out in committee by representatives of the Big Three; the French would be invited to occupy a portion of the Anglo-American zone; Germany would pay reparations to the Allies with the details again to be worked out by committee representatives of the Big Three; 3. The Soviets would enter the war against Japan "in two or three months after Germany has surrendered, and the war in Europe has terminated ''I' provided that the: (a) status quo in Outer Mongolia would be preserved; (b) territories and commercial/military rights "violated by the treacherous attack of Japan in 1904 ''~'would be restored; (c) Kurile Islands would become part of the Soviet Union. d The "Protocol of the Proceedings of the Yalta Conference" appear on pages 625-632 of The Semblance of Peace. 12 4. The portion of Poland east of the "Curzon Line" would be in the Soviet sphere of influence; as compensation, Poland would gain territory to itswest, the delimitation of which would be decided at the eventual peace conference; 5. The European peoples liberated from domination by Nazi Germany would be given the rights assured by the Atlantic Charter - namely the rights of political self-determination and the restoration of sovereignty; however, To foster the conditions in which the liberated peoples may exercise these rights, the three governments will jointly assist the people in any European liberated state or former Axis satellite in Europe where in their judgment conditions require (a) to establish conditions of internal peace; (b) to carry out emergency measures for the relief of distressed peoples; (c) to form interim governmental authorities broadly representative of all democratic elements in the population and pledged to the earliest possible establishment through free elections of governments responsive to the will of the people; and (d) to facilitate where necessary the holding of such elections." In summary, the plans agreed to at Yalta paved the way for continued mistrust among the members of the Grand Alliance. While each of the Big Three could claim that their major objectives had been met, it was an even stronger Stalin who emerged from the conference. In the coming months, the Soviet dictator would exploit the vagaries of the language concerning Poland and the "liberated peoples" of Eastern Europe to further his agenda for subjugating Eastern Europe to Soviet rule. His willingness to test the resolve of his Anglo-American allies, especially the new American president, would prove to be a determining factor in the timing of Truman's decision to use the atomic bomb against Japan. Truman Franklin Roosevelt died suddenly on 12 April 1945, just two months after the conclusion of the Yalta Conference. The new President, Harry Truman, had been elected to the Senate in 1934 where he served until his selection as Roosevelt's running mate on the 1944 ticket. Truman's foreign policy experience was extremely limited and Roosevelt had neglected to discuss national security issues with his new vice president. At this most critical juncture in history, the 13 American president knew almost nothing of his predecessor's grand strategy for ending the war and shaping the postwar world. In particular, he was ignorant of the pact between Roosevelt and Churchill which was consummated by the signing of the Quebec Agreement in August 1943 and reaffirmed at Hyde Park in September 1944. zt Further, Truman was a virtual stranger to both Churchill and, more importantly, Stalin. In the days following Roosevelt's death, Ambassador Averill Harriman informed Truman from Moscow that Stalin was planning to recant on the spirit of the Yalta agreements by recognizing a puppet communist government in Poland. It also appeared that Stalin was being recalcitrant on his commitment to the formation of the United Nations. Truman and Stalin would continue to discuss these and other issues over the next several months, but the net effect was that the inexperienced American president soon hardened his resolve to show the Soviet leader that he would not be bullied into allowing the Russians to renege on the agreements made at Yalta. Secretary of War Stimson briefed President Truman on the status of the atomic bomb project on 25 April. be ready for use within He informed the president that the bomb would likely four months. Stimson never mentioned the possible targeting of Japan, and generally avoided discussion of specifics. Rather, he urged Truman to appoint a committee that would address the questions of how, when and to what effect the bomb might be used. Truman approved Stimson's recommendation and the Interim Committee was established with Stimson as its chairman. Vannevar Bush and James Conant were also assigned to serve on the committee. 14 The Interim Committee The Interim Committee met several times in May with Army Chief of Staff General George Marshall and General Leslie Groves attending as time permitted." Discussions centered more on how the twd bombs expected to be ready by August should be used rather than if they should be used. With the unconditional surrender of Germany on 8 May, the committee determined that Japan should be targeted. The idea of merely demonstrating the bomb was rejected. felt that the Japanese First, it was hierarchy would view such a demonstration as an idle threat - they would never believe that the United States would actually employ the bomb as a weapon against them. Second, even the project's scientists could not guarantee that the bomb would work as advertised. Giving the Japanese prior warning of either the date or location of an attack was also rejected. Committee members feared that the Japanese might intercept the American B-29 enroute to its target, thereby jeopardizing the success of any attack. the Japanese would move American prisoners-of-war There was also fear that into the target area. morality of dropping the bombs on Japanese cities was hardly an issue. the committee determined that the expected number of casualties The In fact, would not substantially exceed those of the 9-10 March firebombing raids on Tokyo. f The committee next discussed the postwar implications of using the bomb. They realized that its effectiveness as a coercive diplomatic lever against the Soviet Union would only last until the Soviets had acquired their own atomic bombs. Also of concern was whether continuing to keep the bomb's existence from the Soviets would lead to future difficulties in maintaining cooperative relations. ' Truman's decision to use both bombs was a single decision that would be based on the recommendation of the Interim Committee. f The Tokyo raids killed 85,000 persons and injured 40,000. Over 1 million people were left homeless (The Great Decision: 77). The February 1945 firebombings of Dresden, Germany, killed an estimated 135,090 people (Truman: 393). 15 The committee vigorously debated how long it would take the Soviet Union to develop their own nuclear capability once the "secret" of the bomb was out. General Groves, who had taken the strictest measures to maintain security in the Manhattan Project W, estimated that it would be twenty years before the Soviets were able to build their own atomic bomb. Far more conservative and, as it turned out, accurate was the estimate of only four years made by Bush and Conant." The Interim Committee's work was finished on 1 June 1945" and its report was presented to President Truman on 6 June by Stimson." The report i unanimously recommended that: 1. The bomb should be used against Japan as soon as possible. 2. It should be used against a military target surrounded by other buildings. 3. It should be used without prior warning of the nature of the weapon." Stimson also discussed the idea of possibly using the bomb as a lever in postwar negotiations with the Soviet Union. z' Thus, the president was now fully cognizant of his predecessor's plans for achieving the dual objectives of winning the war and demonstrating the new Anglo-American power to Stalin. The impetus for the decision to use the atomic bomb had grown immeasurably stronger with the work of the Interim Committee. Once the military and political ' Much to the displeasure of the scientists working on the Manhattan Project, Groves compartmentalized most of the information pertaining to bomb development. The scientists' objections that such compartmentalization hampered the exchange of ideas and actua]ly lengthened the development process seems, in retrospect, to be valid (A World destroyed: 58-63). Even with the strict security imposed by General Groves, the Soviets had already learned many of the secrets of the Manhattan Project. Klaus Fuchs, a Russian spy working at Los Alamos, had been feeding information to Moscow through Anatoli Yakovlev, the Russian vice consul in New York (Day One: 217-220). J The entire Interim Committee report may be found on pages 295-304 of World Destroyed. 16 costs of a full-scale invasion of Japan were added to the weight of the committee's recommendations, the advantages of using the bombs against Japan would prove impossible for the president to counterbalance. Plans for the Invasion of Japan By all military intelligence estimates in the spring of 1945, Japanese forces were seen to be in dire straits, but there was little evidence that their political masters were inclined to surrender unconditionally. Thus, during April and May of 1945, General Douglas MacArthur and Admiral Chester Nimitz made plans for an attack on Japan. The Navy leadership in Washington (primarily Admiral Leahy and U.S. Fleet Commander Admiral Ernest King) favored continued aerial bombardment and naval blockade of the Japanese islands. They believed that such pressure would bring about Japan's collapse without the cost of a massive invasion. The Army strategists, heavily influenced by MacArthur's views, argued that the Navy's strategy could extend the war for years at no less a cost in men and materiel than an invasion. To further make their case, they pointed to the fact that unrelenting air bombardment had previously proven unsuccessful in breaking the will of the Germans to continue fighting in the European war. The debate ended when Admiral King finally agreed to a large-scale invasion after Nimitz sided with MacArthur. z' The Joint Chiefs of Staff presented their plans for the invasion of Japan to President Truman on 18 June. 250,000 and 1 million men. z' They indicated that casualties could range between The plan tentatively approved by Truman called for: 1. A i r bombardment and b l o c k a d e of J a p a n from b a s e s i n Okinawa, Iwo J i m a , t h e M a r i a n a s , and t h e P h i l i p p i n e s . 2. A s s a u l t of Kyushu on 1 November 1945, and t h e i n t e n s i f i c a t i o n of blockade and air bombardment. 3. Invasion of the industrial heart of Japan through the Tokyo Plain, in central Honshu, tentative start date 1 March 1946." 17 Soviet entry into the war was still desired as a means of assuring that Japanese forces fighting elsewhere, especially those on the mainland of Asia, would also surrender. If the Soviets held to the commitment they made at Yalta, their intervention against Japan could be expected within three months from the date of Germany's surrender. Hence their entry into the war would be no later than 8 August 1945. As it would turn out, fear of the future implications of Soviet entry into the war would contribute to President Truman's decision to use the atomic bomb as soon as possible after the conclusion of the Potsdam Conference. Potsdam With the winning of the war now in sight, efforts were in progress to arrange a meeting for Truman with Churchill and Stalin at Potsdam, near Berlin. that ground testing of the atomic bomb was planned rescheduled the Potsdam Conference to begin on 15 July. his Grand Alliance partners, for mid-July, Knowing Truman Before he conferred with the president wanted to be sure that the atomic bombs would be ready for use against Japan.

Stalin greatly resented Truman's coy avoidance of telling him directly of the existence of the atomic bomb. Soon after the first atomic bomb was dropped, Stalin told big own atomic scientists "'Provide us with atomic weapons in the shortest possible time. You know that Hiroshima has shaken the whole world. The balance has been destroyed. Provide the bomb - it will remove a great danger to us.'" (Day One: 226) 20 While there was some lively debate among Japanese leadersover accepting the terms of the proclamation k, it came as no surprise to the Allies when, on 28 July, Japan rejected the terms of the Potsdam Declaration. i The "unforeseen circumstances" vaguely alluded to on 24 July at Potsdam had not occurred.' Use of the Atonic I ~ : The Decision is Made Move to Preempt the Soviets With the rejection of the Potsdam Declaration, Truman now took the last steps k The entire text of the Potsdam Declaration may be found on pages 376-378 of The Semblance of Peace. t The actual wording of the Japanese response continues to cause a great deal of interpretive debate. It is possible that their use of the word mokusatsu was intended to convey the notion that they "took no notice" of the proclamation. However, American translators believed that the Japanese had stated that they had chosen to "ignore" it. (The Semblance of Peace: 379-380) While certain historians agonize over whether the dropping of the atomic bombs could have been avoided had mok,satsu not been interpreted as a rejection of the Potsdam Declaration, I am of the opinion that it would not have mattered in any case. The confluence of reasons for using the atomic bombs had all but made the attacks against Japan a foregone conclusion that could only have been avoided had the Japanese imediately and fully accepted the terms of the proclamation. • On 25 July, Truman ordered Lieutenant General Carl A. Spaatz, Commander of U.S. Army Strategic Air Forces in the Pacific, to drop the "first special bomb as soon as weather will permit visual bombing after about 3 August 1945 on one of the targets: Hiroshima, Kokura, Niigata, and Nagasaki." Spaatz delegated the decision of when to conduct the actual bombing to Major General Curtis E. LeMay. Thus, the military was given ample time to prepare to execute the order Truman felt he would likely issue if, as he probably anticipated, the Japanese rejected the terms of the Potsdam Declaration. (Command Decisions: 514) During June and July, General Groves had been working on a target list for the atomic bomb drops. He had preferred the cities of Kyoto (the holy city which had once been the Japanese capital} and Tokyo for the devastating psychological effect that could bring about the rapid capitulation of the Japanese. Stimson overruled the General, not for humanitarian concerns, but because he feared that such a mortifying blow to the Japanese might make them turn to the Soviets rather than the United States during the long postwar reconciliation period. (Day One: 227) 21 towards finalizing his decision to use the atomic bombs against Japan. With the atomic bombs ready to be used, Truman's military advisors had convinced him that Soviet intervention against Japan was not necessary. Further, there was consternation over the political implications of the Soviets' 8 August date for entry into the war. During the Potsdam Conference, Stalin had belligerently pressed for an increased Soviet presence in Europe (including bases in Turkey) and it was clear that intervention against Japan would enable Moscow to exercise control over Manchuria and Outer Mongolia. After three years of urging Stalin to declare war against Japan, culminated by the concessions to the Russian made by Roosevelt at Yalta, Truman could not reasonably ask Stalin to stay out of the war. Even if he had done so, there was scant reason to believe that Soviet intervention could have been precluded." Only one thing could prevent the Soviets from playing a major role in concluding the war against Japan. On 31 July, as the call for unconditional surrender continued to be met with silence, Truman ordered the first nuclear strikes in history.' While it would be the Japanese cities of Hiroshima and Nagasaki that would suffer the terrible destruction wrought by the atomic bombs, the secondary target of the bombs was the Soviet Union. niroshima and Nagasaki On 6 August 1945, Colonel Paul Tibbets, commander of the 509th Composite Group, piloted the Enola Gay over Hiroshima. atomic bomb, at 8:15 A.M. The B-29 dropped its payload, a single Forty-five seconds later, the city of Hiroshima was leveled in a searing flash of heat, light, shock, and fire. Nearly 100,000 ' The president issued the following handwritten message: "Suggestions approved. Release when ready but not sooner than August 2. HST." Truman was scheduled to leave Potsdam on 2 August and it was likely that he intended to avoid having to explain the dropping of the bomb to Stalin. (Day One: 230) 22 people were killed instantly, with thousands more to perish later of burns, shock, and radiation poisoning. A statement was issued from the White House within hours announcing the existence of the atomic bomb and warning the Japanese to surrender immediately or "they may expect a rain of ruin from the air, the like of which has never been seen on this earth. ''u In Tokyo, Japanese Foreign Minister Togo, War Minister Anami, and Prime Minister Suzuki debated the meaning of the Hiroshima attack August. for the remainder of 6-7 They could not be sure whether Hiroshima had been victimized by an atomic bombing as claimed by the Americans or merely a massive firebombing raid such as had been seen previously. Their worst fears were confirmed on the evening of 7 August when a scientific team dispatched to Hiroshima reported that the city had, in fact, been devastated by an atomic bomb. u During the afternoon of 8 August, Togo briefed Hirohito and the Emperor instructed the Foreign Minister to hasten his efforts to gain Suzuki's acceptance of the terms of the Potsdam Declaration: "'Since the nation can no longer continue the struggle with this weapon opposing it, Japan should not miss the chance for peace by vain efforts to secure better terms.'" A meeting of the Supreme War Council was scheduled for the morning of 9 August.

The Japanese surrendered and World War II was over. In Retrospect: Should We Have Used the ltomic Bombs? The morality of using the atomic bombs was never really an issue for political and military leaders of the United States and Great Britain. the While some, such as Admiral Leahy, questioned whether the bombs would actually work, virtually none had doubts that the bombs should be employed as military weapons against the Japanese - especially if so doing obviated the need for a long and costly invasion.' There are two key questions to be addressed. First, was destroying two more Japanese cities with bombs that were expected to be as dreadful in their effects as the terrible conclusion? firebombing Second, was raids using necessary the atomic to bring bombs an the war to effective a means swift for controlling Stalin's expansionist designs in the postwar world? My answers respectively. to these questions are "probably not" and "definitely not", I contend that Truman would have done better by pursuing a well- conceived policy of diplomacy with both Japan and the Soviet Union. Before I present my case, however, it is important to step back and revisit the AngloAmerican atomic monopoly. ' Churchill later wrote of the meeting on 24 July at Potsdam: "The historic fact remains, and must be judged in the after-time, that the decision whether or not to use the atomic bomb to compel the surrender of Japan was never an issue. There was unanimous, automatic, unquestioned agreement around our table; nor did I ever hear the slightest suggestion that we should do otherwise." Truman later said: "The final decision of where and when to use the atomic bomb was up to me. Let there be no mistake about it. I regarded the bomb as a military weapon and never had any doubt that it should be used. The top military advisors to the President recommended its use, and when I talked to Churchill he unhesitatingly told me that he favored the use of the atomic bomb if it might aid to end the war." (Truman: 442) 24 Churchill and Roosevelt Revisited It is difficult for me to quarrel with historically great men such as Winston Churchill and Franklin Roosevelt. If they believed that the best way to ensure Anglo-American control over the Soviets in the postwar world was to keep their atomic monopoly a secret from Stalin, challenge their decision. I would not be so presumptuous as to If they rejected the concerns of the scientists and diplomats who warned of an impending Cold War and nuclear arms race, I could understand how they might have believed that the Cold War had already begun despite their efforts to placate Stalin with concessions made at Yalta. Certainly, Stalin's intransigence following the conference gave little indication that he could be trusted. Further, Roosevelt and Churchill could not have known that it would take only until 1949 before the Soviets developed their own atomic bomb. P Perspective on Truman Truman's decision to use the atomic bombs against Japan must be evaluated in the context of how well it accomplished two very differe.t strategic objectives. The first objective was to compel the Japanese to surrender unconditionally without incurring the costs of a massive invasion. This objective was £.]]y achieved. The second objective, essentially a legacy of the Churchill/Roosevelt atomic monopoly, was to demonstrate a uniquely powerful military weapon as a means for creating future political advantages over the Soviet Union. This objective was partia]lyachievedin that Stalin was prevented from making a great impact in the Far East. However, the extent to which the United States was able to exploit any political advantages following the conclusion of the war must be balanced against the loss of Eastern Europe to the Soviets {necessitating the policy containment) and the inception of the Cold War and the nuclear arms race. 25 of Returning to the second of the two questions raised above, using the atomic bombs was definitely not an effective designs in the postwar world. means for controlling Stalin's expansionist Nor was Truman wise to keep the existence of the bomb a secret from Stalin at Potsdam in so far as it perpetuated Soviet mistrust of the United States and, at the very least, exacerbated Cold War tensions between the East and West. Many revisionist historians (most prominently Martin Sherwin) claim that Truman's primary reason for using the bomb was to achieve postwar diplomatic leverage over the Soviet Union. In his recent book, Truman, David McCullough disagrees, arguing that Truman's goals coincided exactly with what actually occurred. With the successful test of the bomb at Alamogordo, the invasion contingency was all but moot. McCul]ough stresses that Truman's sole objective was to compel the Japanese to unconditionally surrender before the Soviets could enter the war. He rejects the notion that Truman wanted to send an atomic message to Stalin. He states that Truman looked upon himself as being an extremely persuasive man who, unlike his irascible British counterpart Churchill, thought he could deal with Stalin's intransigence. Let's assume that McCullough's suppositions are accurate. ~ accomplished his objective without using Could Truman have the atomic weapons against Japan? ~ Probably not, unless he were willing to back away from adamantly refusing to ' It is entirely possible that McCullough is wrong. It must have been very difficult for Truman to completely reject the Churchill/Roosevelt strategy for controlling Stalin's expansionist designs in the postwar world. There is no way of actually knowing how important this goal was for Truman, but if he was committed to trying to achieve it, then demonstrating the bomb at Hiroshima was probably the only way he could have done it. ' Obviously, Truman achieved this objective and the United States became the sole arbiter of Japan's postwar reconstruction - but at what cost to our moral credibility among the nations of the world? 26 provide assurances to the Japanese leadership that Emperor Hirohito would be retained. First, In my view, that is precisely what President Truman should have done. the language in the Potsdam Declaration should have more specifically addressed Japanese concerns over the future of their Emperor. "Unconditional surrender" was a term that should not have been so lightly used with the Japanese hierarchy. As it was worded, the Potsdam Declaration left open the possibility that Hirohito could be prosecuted as a war criminal. While this approach was certainly appropriate for the political and military leaders of the defeated Germany, it was inconceivable that the Japanese would countenance such a veiled threat to their god-likeEmperor. Second, the Potsdam Declaration should have set a fixed date (perhaps 1 August) for Japanese acceptance of a cease fire with peace negotiations scheduled to immediately follow. If possible, Truman should have tried to get Stalin to agree to dates that would delay Soviet entry into the war. It should have been made clear to the Japanese to be concluded that negotiations would need to the satisfaction of the Allies within a short period of time (perhaps 15 August), otherwise the United States would resume the war with all the resources at its disposal. The threat of total destruction should still have been made, but should have been contingent on Japan's failure to conclude a peace agreement acceptable to the Allies within the specified time. The Japanese should have been told that they must deal directly with the United States and not try to work through intermediaries in Moscow. Third, if the plan described surrender, Truman should above did not result have ordered that Hiroshima (perhaps as early as 16 August). 27 the in the desired atomic bomb terms of be dropped on He should not have issued a single order authorizing t h e use of b o t h bombs. Fourth, following Hiroshima, Truman should again have been more specific in his language rather than merely threatening Japan with continued destruction from the air. He should have set reasonable deadlines for Japanese compliance with his demands for an end to hostilities and a peried of negotiation. Knowing how long it takes to make a major decision in our own political system, Truman should have afforded the Japanese leaders at least a week to respond. Faced with American threats of further nuclear destruction and the Soviet's entry into the war, Japanese leaders would likely have knuckled under pressure from Emperor Hirohito to surrender within the allotted time frame. Fifth, and only if the Japanese still refused to capitulate r, Truman should have proceeded with a new order to drop the second atomic bomb on Nagasaki. In my estimation, following the approach described above would have had a reasonable chance for quickly winning the war against Japan before the Soviets could gain a foothold in Manchuria or Outer Mongolia and without having to resort to using nuclear weapons. Returning to the first question addressed above, was decimating two more Japanese cities with bombs that were expected to be as dreadful in their effects as the terrible firebombing raids necessary to bring the war to a swift conclusion? My answer is probably not for Hiroshima, and almost certainly not for Nagasaki. r If, in fact, Truman did intend to send an atomic message to Stalin, he had already done that with the bombing of Hiroshima. A second bombing at Nagasaki would have added nothing towards accomplishing that goal. 28 Conclusion I believe that had Franklin Roosevelt lived, he would have used the atomic bombs primarily to influence Soviet behavior in the postwar world. Roosevelt felt that Stalin was traditional diplomatic means. too incorrigible to Like Churchill, be dealt with using In their view, "atomic diplomacy" was the only way to effectively project Anglo-American political power against the vast military strength of the Soviet Union under the iron-listed leadership of Joseph Stalin. Unlike his predecessor, the inexperienced Harry Truman of 1945 seems not to have been a long-range strategic thinker.' He placed great trust in his own abilities to convincingly sway even the most belligerent opponent in face-to-face confrontations. This is likely the reason that after Stalin continued to behave truculently after the war, Truman felt such disappointment that he never again met with him personally. In the end, I agree with McCullough's characterization of Truman's motives for using the atomic bombs. separate decisions. However, I would argue that Truman actually made two The decision to use the bombs was driven by his desire to force the Japanese to surrender unconditionally. The timing of when to use the bombs was driven by his desire to keep the Soviets out of the Far East. When viewed in this way, it is clear to see why any bombing delay beyond Potsdam was not an option for Truman. While he thought that by force of personality he could control Stalin's designs on Eastern Europe after the war, he realized that there was no way to preclude Soviet gains in the Far East unless the war ended immediately. ' As he m a t u r e d i n t h e p r e s i d e n c y , Truman d i d d i s p l a y b r i l l i a n t strategic v i s i o n i n t h e f o r m u l a t i o n of t h e M a r s h a l l P l a n , t h e a i r l i f t to break the Soviet b l o c k a d e o f B e r l i n , and t h e i m p l e m e n t a t i o n of t h e p o l i c y of c o n t a i n m e n t . 29 The ironic tragedy of the decision to use the atomic bombs cannot be avoided. In our postwar rebuilding of Japan, we implemented a new constitution and democratic government, yet the ceremonial role of the Emperor has been retained even unto the present time. Like a stern, but loving parent disciplining a rebellious child, Truman had obstinately insisted that the Japanese surrender his way (unconditionally with no negotiations), only to cede to their wishes (to keep the Emperor) after they had done so. In order to get his way, Truman punished the Japanese most severely, but without considering how their national psyche made it virtually impossible for them to comply with his wishes.
