Interested readers will continue to absorb the fascinating historical literature on the subject. [40], L.D. This latest iteration of the collection includes corrections, a few minor revisions, and updated footnotes to take into account recently published secondary literature. The author recommended issuing the declaration just before the bombardment program [against Japan] reaches its peak. Next to that suggestion, Stimson or someone in his immediate office, wrote S1, implying that the atomic bombing of Japanese cities was highly relevant to the timing issue. One of the reports key findings was that a fission bomb of superlatively destructive power will result from bringing quickly together a sufficient mass of element U235. That was a certainty, as sure as any untried prediction based upon theory and experiment can be. The critically important task was to develop ways and means to separate highly enriched uranium from uranium-238. [46]. The question is: The Untied States decision to drop the atomic bomb on Hiroshima was a diplomatic measure calculated to intimidate the Soviet Union in the post-Second-World-War era rather then a strictly military measure designed to force Japan's unconditional suuender. Washington, D.C., August 5, 2005 - Sixty years ago this month, the United States dropped atomic bombs on Hiroshima and Nagasaki, the Soviet Union declared war on Japan, and the Japanese government surrendered to the United States and its allies. Bernstein, introduction,Toward a Livable World, xxxvii-xxxviii. With more information on the Alamogordo test available, Groves provided Marshall with detail on the destructive power of atomic weapons. All Rights Reserved, FJHUMMING: Radio Libertys Russian Language Broadcasts from Taiwan, 75th Anniversary of the Atomic Bombing of Hiroshima and Nagasaki. Note: The second page of the diary entry includes a newspaper clipping of the Associated Presss transmission of the Byrnes note. Eisenhower and McCloys Views on the Bombings and Atomic Weapons, National Security Archive This diary entry has figured in the argument that Byrnes believed that the atomic bomb gave the United States a significant advantage in negotiations with the Soviet Union. Social critic Dwight MacDonald published trenchant criticisms immediately after Hiroshima-Nagasaki; seePolitics Past: Essays in Political Criticism(New York: Viking, 1972), 169-180. For casualty figures and the experience of people on the ground, see Frank, 264-268 and 285-286, among many other sources. As the scientists had learned, a gun-type weapon based on plutonium was impossible because that element had an unexpected property: spontaneous neutron emissions would cause the weapon to fizzle.[10] For both the gun-type and the implosion weapons, a production schedule had been established and both would be available during 1945. The National Security Archive is committed to digital accessibility. [31]. President Truman, who ordered the bomb, defended it as a way to bring about surrender and save U.S. military lives that would have been lost in a ground invasion of Japan. The first bomb was dropped on Hiroshima at 8:15 AM on August 6th, and the second bomb was dropped over Nagasaki on August 9th at 11:02 AM. This account hints at discussion of the atomic bomb (certain other matters), but no documents disclose that part of the meeting. Fears and Counterfactual Analysis: Would the Planned November 1945 Invasion of Southern Kyushu Have Occurred?Pacific Historical Review68 (1999): 561-609. The bombings have always been presented to young Americans in . With respect to the latter, It is possible that the destructive effects on life caused by the intense radioactivity of the products of the explosion may be as important as those of the explosion itself. This insight was overlooked when top officials of the Manhattan Project considered the targeting of Japan during 1945. Harriman Papers, Library of Congress, box 211, Robert Pickens Meiklejohn World War II Diary At London and Moscow March 10, 1941-February 14, 1946, Volume II (Privately printed, 1980 [Printed from hand-written originals]) (Reproduced with permission), Robert P. Meiklejohn, who worked as Ambassador W. A. Harrimans administrative assistant at the U.S. Embassies in Moscow and London during and after World War II, kept a detailed diary of his experiences and observations. Barton J. Bernsteins numerous articles in scholarly publications (many of them are listed in Walkers assessment of the literature) constitute an invaluable guide to primary sources. On August 6, 1945 the American war plane Enola Gay dropped an atomic bomb on Hiroshima, killing between 70,000 and 100,000 Japanese. The task of compilation involved consultation of primary sources at the National Archives, mainly in Manhattan Project files held in the records of the Army Corps of Engineers, Record Group 77, but also in the archival records of the National Security Agency. National Archives Identifier 535795] RG 77, MED Records, H-B files, folder no. Drawing on sources at the National Archives and the Library of Congress as well as Japanese materials, this electronic briefing book includes key documents that historians of the events have relied upon to present their findings and advance their interpretations. Tagaki was soon at the center of a cabal of Japanese defense officials, civil servants, and academics, which concluded that, in the end, the emperor would have to impose his decision on the military and the government. Takagi kept a detailed account of his activities, part of which was in diary form, the other part of which he kept on index cards. Would the Soviet declaration of war have been enough to compel Tokyo to admit defeat? Churchill and India: Manipulation or Betrayal? 1. Hasegawa, 105; Alperovitz, 67-72; Forrest Pogue,George C. Marshall: Statesman, 1945-1959(New York: Viking, 1987), 18. The Soviets already knew about the U.S. atomic project from espionage sources in the United States and Britain so Molotovs comment to Ambassador Harriman about the secrecy surrounding the U.S. atomic project can be taken with a grain of salt, although the Soviets were probably unaware of specific plans for nuclear use. With the goal of having enough fissile material by the first half of 1945 to produce the bombs, Bush was worried that the Germans might get there first. Documents 77A-B: The First Japanese Offer Intercepted. Three days later, it dropped another on Nagasaki. Moreover, ethical questions have shrouded the bombings which caused terrible human losses and in succeeding decades fed a nuclear arms race with the Soviet Union and now Russia and others. Explain your answer. The warning would draw on the draft State-War proclamation to Japan; presumably, the one criticized by Hull (above) which included language about the emperor. Also documented are U.S. decisions to target Japanese cities, pre-Hiroshima petitions by scientists questioning the military use of the A-bomb, proposals for demonstrating the effects of the bomb, debates over whether to modify unconditional surrender terms, reports from the bombing missions of Hiroshima and Nagasaki, and belated top-level awareness of the radiation effects of atomic weapons. Taking the Americans by surprise, the Japanese planes destroyed or damaged 18 ships . Willingness to accept even the destruction of the Army and Navy rather than surrender inspired the military coup that unfolded and failed during the night of 14 August. Some months later, with the Manhattan Project already underway and under the direction of General Leslie Grove, Bush outlined to Roosevelt the effort necessary to produce six fission bombs. In contrast to Alperovitzs argument that Forrestal tried to modify the terms of unconditional surrender to give the Japanese an out, Frank sees Forrestals account of the Sato-Togo exchange as additional evidence that senior U.S. officials understood that Tokyo was not on the cusp of surrender. [49], Joseph E. Davies Papers, Library of Congress, Manuscripts Division, box 19, 29 July 1945, Having been asked by Truman to join the delegation to the Potsdam conference, former-Ambassador Davies sat at the table with the Big Three throughout the discussions. [6]. Those and other questions will be subjects of discussion well into the indefinite future. This was the affirmation of the emperors theocratic powers, unencumbered by any law, based on Shinto gods in antiquity, and totally incompatible with a constitutional monarchy. Thus, the Japanese response to the Potsdam declaration opposed any demand which prejudices the prerogatives of his Majesty as a sovereign ruler. This proved to be unacceptable to the Truman administration.[63]. Atomic Bomb Radiation - bomb made from uranium which is highly toxic - long term effects of exposure led to increased cancer rates Instrument of Surrender the written agreement that formalized the surrender of the Empire of Japan, marking the end of World War II emperor clause included but edited from the original draft of Potsdam [67], National Archives, RG 165, Army Operations OPD, Executive Files 1940-1945, box 12, Exec #2. Today, historians continue to debate this decision. The target is and was always expected to be Japan., These documents have important implications for the perennial debate over whether Truman inherited assumptions from the Roosevelt administration that the bomb would be used when available or that he madethedecision to do so. Historians Herbert Feis and Gar Alperovitz raised searching questions about the first use of nuclear weapons and their broader political and diplomatic implications. The United States, along with other countries, criticized Japanese aggression but shied away from any economic or military punishments. In reply, Roosevelt wrote a short memo endorsing Bushs ideas as long as absolute secrecy could be maintained. 100 (copy from microfilm). Barton J. Bernsteins 1987 article, Ike and Hiroshima: Did He Oppose It?The Journal of Strategic Studies10 (1987): 377-389, makes a case against relying on Eisenhowers memoirs and points to relevant circumstantial evidence. Relations between the United States and Japan worsened when Japanese forces took aim at Indochina with the goal of capturing oil rich areas of the East Indies. That there may be a difference between the two sources becomes evident from some of the entries; for example, in the entry for July 18, 1945 Brown wrote: "Although I knew about the atomic bomb when I wrote these notes, I dared not place it in writing in my book., The degree to which the typed-up version reflects the original is worth investigating. How decisive was the atomic bombings to the Japanese decision to surrender? At 10:50 a.m., he met with the leadership at the bomb shelter in his palace. Women and children had been taught how to kill with basic weapons. Stalin considered various dates to schedule an attack. [18]. Atomic diplomacy refers to attempts to use the threat of nuclear warfare to achieve diplomatic goals. Pumpkins referred to bright orange, pumpkin-shaped high explosive bombsshaped like the Fat Man implosion weapon--used for bombing run test missions. According to the official US version of history, an A-bomb was dropped on Hiroshima on 6 August 1945, and another on Nagasaki three days later, to force Japan to surrender. To what extent did subsequent justification for the atomic bomb exaggerate or misuse wartime estimates for U.S. casualties stemming from an invasion of Japan? At their first meeting after the dropping of the bomb on Hiroshima, Stimson briefed Truman on the scale of the destruction, with Truman recognizing the terrible responsibility that was on his shoulders. It was a decision to loose the most terrible of all destructive forces for the wholesale slaughter of human beings. Read more, The Nuclear Proliferation International History Project is a global network of individuals and institutions engaged in the study of international nuclear history through archival documents, oral history interviews, and other empirical sources. Some may associate this statement with one that Eisenhower later recalled making to Stimson. This report included an intercept of a message from Sato reporting that it was impossible to see Molotov and that unless the Togo had a concrete and definite plan for terminating the war he saw no point in attempting to meet with him. The last major battle, the fight for Okinawa, lasted almost three months and took more than 100,000 Japanese and American lives. When the Foreign Minister met with the Emperor, Hirohito agreed with him; he declared that the top priority was an early end to the war, although it would be acceptable to seek better surrender terms--probably U.S. acceptance of a figure-head emperor--if it did not interfere with that goal. For a useful discussion of the firebombing of Tokyo and the atomic bombings, see Alex Wellerstein, Tokyo vs. Hiroshima,Restricted Data: The Nuclear Secrecy Blog,22 September 2014. Thus, Groves and others would try to suppress findings about radioactive effects, although that was a losing proposition.[76]. [41]. Sadao Asada emphasizes the shock of the atomic bombs, while Herbert Bix has suggested that Hiroshima and the Soviet declaration of war made Hirohito and his court believe that failure to end the war could lead to the destruction of the imperial house. According to an Eyewitness Account (and Estimates Heard) In Regard to the Bombing of Hiroshima: Casualties have been estimated at 100,000 persons., Zenshiro Hoshina, Daitoa Senso Hishi: Hoshina Zenshiro Kaiso-roku [Secret History of the Greater East Asia War: Memoir of Zenshiro Hoshina] (Tokyo, Japan: Hara-Shobo, 1975), excerpts from Section 5, The Emperor made go-seidan [= the sacred decision] the decision to terminate the war, 139-149 [translation by Hikaru Tajima]. The editor has closely reviewed the footnotes and endnotes in a variety of articles and books and selected documents cited by participants on the various sides of the controversy. And on Aug. 6, a bomb would fall on Hiroshima, ultimately killing an. Bix appears to have moved toward a position close to Hasegawas; see Bix, Japan's Surrender Decision and the Monarchy: Staying the Course in an Unwinnable War,Japan Focus. By contrast, Maddox argues that Nagasaki was necessary so that Japanese hardliners could not minimize the first explosion or otherwise explain it away. The 70th anniversary of the event presents an opportunity to set the record straight on five widely held myths about the bomb. Victims who looked healthy weakened, for unknown reasons and many died. 2 Pt. On 30 October 1961, the Soviet Union detonated the Tsar Bomba nuclear bomb over the Novaya Zemlya archipelago in northern Russia. [35]. An important question that Stimson discussed with Marshall, at Trumans request, was whether Soviet entry into the war remained necessary to secure Tokyos surrender. The atomic bomb on Hiroshima. Also included, to give a wider perspective, were translations of Japanese documents not widely available before. That goal, he feared, raised terrifying prospects with implications for the inevitable destruction of our present day civilization. Once the U.S. had used the bomb in combat other great powers would not tolerate a monopoly by any nation and the sole possessor would be be the most hated and feared nation on earth. Even the U.S.s closest allies would want the bomb because how could they know where our friendship might be five, ten, or twenty years hence. Nuclear proliferation and arms races would be certain unless the U.S. worked toward international supervision and inspection of nuclear plants. Thanks to Alex Wellerstein for the suggestion and the archival link. [62]. Moreover, the collection includes for the first time translations from Japanese sources of high level meetings and discussions in Tokyo, including the conferences when Emperor Hirohito authorized the final decision to surrender. . How is the current debate about immigration in the United States rooted in our nations past? [80]. Fax: 202/994-7005Contact by email. [26]. Stimson accepted the language believing that a speedy reply to the Japanese would allow the United States to get the homeland into our hands before the Russians could put in any substantial claim to occupy and help rule it. If the note had included specific provision for a constitutional monarchy, Hasegawa argues, it would have taken the wind out of the sails of the military faction and Japan might have surrendered several days earlier, on August 11 or 12 instead of August 14. McCloy was part of a drafting committee at work on the text of a proclamation to Japan to be signed by heads of state at the forthcoming Potsdam conference. Truman, who had been chair of the Senate Special Committee to Investigate the National Defense Program, said that only on the appeal of Secretary of War Stimson did he refrain and let the War Department continue with the experiment unmolested.. Signed by about 68 Manhattan Project scientists, mainly physicists and biologists (copies with the remaining signatures are in the archival file), the petition did not explicitly reject military use, but raised questions about an arms race that military use could instigate and requested Truman to publicize detailed terms for Japanese surrender. Some years after Trumans death, a hand-written diary that he kept during the Potsdam conference surfaced in his personal papers. At the end, Stimson shared his doubts about targeting cities and killing civilians through area bombing because of its impact on the U.S.s reputation as well as on the problem of finding targets for the atomic bomb. If Russia used a nuclear weapon of any type, "I expect (the president) to say we're in a new situation, and the U.S. will directly enter the war against Russia to stop this government that has . Pogue only cites the JCS transcript of the meeting; presumably, an interview with a participant was the source of the McCloy quote. On August 9, 1945, another bomber was in route to Japan, only this time they were heading for Nagasaki with "Fat Man," another atomic bomb. and offer details on potential protection (protective clothing against a uranium bomb includes rubber and any kind of insulation against electricity). Historians and the public continue to debate if the bombings were justified, the causes of Japan's surrender, the casualties that would have resulted if the U.S. had invaded Japan, and more. The day after he told Sato about the current thinking on Soviet mediation, Togo requested the Ambassador to see Soviet Foreign Minister Vyacheslav Molotov and tell him of the Emperors private intention to send Prince Konoye as a Special Envoy to Moscow.
