According to Bix, Hirohito's language helped to transform him from a war to a peace leader, from a cold, aloof monarch to a human being who cared for his people but what chiefly motivated him was his desire to save a politically empowered throne with himself on it.[70], Hirohito said that he would make a recording of the surrender announcement so that the nation could hear it. [17]. 7 (1), 340-341. The original 2005 posting included a wide range of material, including formerly top secret "Magic" summaries of intercepted Japanese communications and the first-ever full translations from the Japanese of accounts of high level meetings and discussions in Tokyo leading to the Emperors decision to surrender. [50]. But on 7 August, Stalin changed the instructions: the attack was to begin the next day. The proposed script for the Smithsonian exhibition can be seen at Philipe Nobile.

Documents 77A-B: The First Japanese Offer Intercepted. 5b, Despite the reports pouring in from Japan about radiation sickness among the victims of Hiroshima and Nagasaki, General Groves and Dr. Charles Rea, a surgeon who was head of the base hospital at Oak Ridge (and had no specialized knowledge about the biological effects of radiation) dismissed the reports as propaganda. For an important study of how contemporary officials and scientists looked at the atomic bomb prior to first use in Japan, see Michael D. Gordin,Five Days in August: How World War II Became a Nuclear War(Princeton: Princeton University Press, 2007). The Atomic Bombing of Hiroshima and Nagasaki, August 1945 With Truman having ordered a halt to the atomic bombings [See document 78], Marshall wrote on Grove's memo that the bomb was not to be released over Japan without express authority from the President., Library of Congress Manuscript Division, Papers of W. Averell Harriman, box 181, Chron File Aug 10-12, 1945, Japans prospective surrender was the subject of detailed discussion between Harriman, British Ambassador Kerr, and Soviet Foreign Minister Molotov during the evening of August 10 (with a follow-up meeting occurring at 2 a.m.). [36]. 5g. 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. With Secretary of War Stimson presiding, members of the committee heard reports on a variety of Manhattan Project issues, including the stages of development of the atomic project, problems of secrecy, the possibility of informing the Soviet Union, cooperation with like-minded powers, the military impact of the bomb on Japan, and the problem of undesirable scientists. In his comments on a detonation over Japanese targets, Oppenheimer mentioned that the neutron effect would be dangerous to life for a radius of at least two-thirds of a mile, but did not mention that the radiation could cause prolonged sickness. Barton J. Bernstein has observed that Groves recommendation that troops could move into the immediate explosion area within a half hour demonstrates the prevalent lack of top-level knowledge of the dangers of nuclear weapons effects. Every August, newspapers are dotted with stories of Hiroshima and Nagasaki, accompanied by a well-picked-over but never resolved . Thus, Groves and others would try to suppress findings about radioactive effects, although that was a losing proposition.[76]. Alperovitz, 662; Bernstein (1995), 139; Norris, 377. Besides Truman, guests included New York Governor Thomas Dewey (Republican presidential candidate in 1944 and 1948), foreign ambassadors, members of the cabinet and the Supreme Court, the military high command, and various senators and representatives. Searle, `It Made a Lot of Sense to Kill Skilled Workers, 118. 60 inches in diameter and 128 inches long, the weapon weighed about 10,000 pounds and had a yield approximating 21,000 tons of high explosives (Copy from U.S. National Archives, RG 77-AEC), Taken at Tinian Island on the afternoon of August 5, 1945, this shows the tail of the Enola Gay being edged over the pit and into position to load "Little Boy" into the bomb bay. Thus, he wanted Roosevelts instructions as to whether the project should be vigorously pushed throughout. Unlike the pilot plant proposal described above, Bush described a real production order for the bomb, at an estimated cost of a serious figure: $400 million, which was an optimistic projection given the eventual cost of $1.9 billion. On August 10, one day after the bombing of Nagasaki, the . It is quite apparent that the United States did, in fact, drop the two atomic bombs, Little Boy and Fat Man on Hiroshima and Nagasaki respectively for the . In these entries, Meiklejohn discussed how he and others in the Moscow Embassy learned about the bombing of Nagasaki from the OWI Bulletin. Entries for 10 and 11 August cover discussion at the Embassy about the radio broadcast announcing that Japan would surrender as long the Emperors status was not affected. In a progress report, Bush told President Roosevelt that the bomb project was on a pilot plant basis, but not yet at the production stage. 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 target would be a city--either Hiroshima, Kyoto (still on the list), or Niigata--but specific aiming points would not be specified at that time nor would industrial pin point targets because they were likely to be on the fringes a city. RG 218, Central Decimal Files, 1943-1945, CCS 381 (6-4-45), Sec. 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. Hasegawa, 105; Alperovitz, 67-72; Forrest Pogue,George C. Marshall: Statesman, 1945-1959(New York: Viking, 1987), 18. For Harrisons convenience, Arneson summarized key decisions made at the 21 June meeting of the Interim Committee, including a recommendation that President Truman use the forthcoming conference of allied leaders to inform Stalin about the atomic project. a. The 27-tonne Soviet Tsar Bomba was the most powerful weapon ever constructed. Since 2005, the collection has been updated. Try again For convenience, Barton Bernsteins rendition is provided here but linked here are the scanned versions of Trumans handwriting on the National Archives website (for 15-30 July). The thought of invading Japan gave Truman and his advisors pause. Barton Bernstein and Richard Frank, among others, have argued that Trumans assertion that the atomic targets were military objectives suggested that either he did not understand the power of the new weapons or had simply deceived himself about the nature of the targets. Later, he met with Secretary of State Byrnes and they discussed the Manhattan Projects secrecy and the huge expenditures. Colonel John Stone, an assistant to commanding General of the Army Air Forces Henry H. Hap Arnold, had just returned from Potsdam and updated his boss on the plans as they had developed. What was the reaction of the Soviet Union to the atomic bombings of Whether this meant that Truman was getting ready for a confrontation with Stalin over Eastern Europe and other matters has also been the subject of debate. Barton J. Bernstein and Martin Sherwin have argued that if top Washington policymakers had kept tight control of the delivery of the bomb instead of delegating it to Groves the attack on Nagasaki could have been avoided. Barton J. Bernstein has suggested that Trumans comment about all those kids showed his belated recognition that the bomb caused mass casualties and that the target was not purely a military one.[64]. 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. To the extent that the atomic bombing was critically important to the Japanese decision to surrender would it have been enough to destroy one city? Of course, the Allies ignored this for the reason that dropping the atomic bomb on the Japanese cities of Hiroshima and Nagasaki would intimidate Russia. Moreover, the atrocities of the bombs were not made graphically public to the Japanese people until August 6, 1952, when Asahi Graphpublished the issue titled Genbaku higai no shokkai (the first publication of the damages of the atomic bomb). Soviet aircraft had bombed Changchun and Harbin by darkness. Leaflets Warning Japanese of Atomic Bomb | American Experience - PBS Frank, 258; Bernstein (1995), 147; Walker (2005), 322. The point was to keep the bombing mission crew safe; concern about radiation effects had no impact on targeting decisions. For emphasis on the shock of the atomic bomb, see also Lawrence Freedman and Saki Dockrill, Hiroshima: A Strategy of Shock, in Saki Dockrill, ed.,From Pearl Harbor to Hiroshima : the Second World War in Asia and the Pacific, 1941-1945(New York, St. Martins Press, 1994), 191-214. (Truman finally cut off military aid to France to compel the French to pull back). While McCloy later recalled that Truman expressed interest, he said that Secretary of State Byrnes squashed the proposal because of his opposition to any deals with Japan. 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. Stimson, who later wrote up the meeting in his diary, also prepared a discussion paper, which raised broader policy issues associated with the imminent possession of the most terrible weapon ever known in human history., In a background report prepared for the meeting, Groves provided a detailed overview of the bomb project from the raw materials to processing nuclear fuel to assembling the weapons to plans for using them, which were starting to crystallize. Background on the U. S. Atomic Project, III. [13]. See for example, Bernstein (1995), 140-141. How much Power does a President actually have? Photo restoration by TX Unlimited, San Francisco, A nuclear weapon of the "Little Boy" type, the uranium gun-type detonated over Hiroshima. As to how the war with Japan would end, he saw it as unpredictable, but speculated that it will take Russian entry into the war, combined with a landing, or imminent threat of a landing, on Japan proper by us, to convince them of the hopelessness of their situation. Lincoln derided Hoovers casualty estimate of 500,000. Suite 701, Gelman Library Confronting the Problem of Radiation Poisoning, XII. For useful discussion of this meeting and the other Target Committee meetings, see Norris, 382-386. After reviewing the impact of various atomic bomb effects--blast, heat, flash radiation (prompt effects from gamma and neutron radiation), and radiation from radioactive substances--they concluded that it seems highly plausible that a great many persons were subjected to lethal and sub-lethal dosages of radiation in areas where direct blast effects were possibly non-lethal. It was probable, therefore, that radiation would produce increments to the death rate and even more probable that a great number of cases of sub-lethal exposures to radiation have been suffered.[74], RG 77, MED Records, Top Secret Documents, File no. Cited in Barton J. Bernstein, Truman and the A-Bomb: Targeting Noncombatants, Using the Bomb, and His Defending the "Decision,The Journal of Military History62 (1998), at page 559. Sato cabled Togo earlier that he saw no point in approaching the Soviets on ending the war until Tokyo had concrete proposals. Any aid from the Soviets has now become extremely doubtful.. Bernstein (1995), 146. Why we dropped the Atomic Bomb The dropping of the atomic bombs on Hiroshima and Nagasaki in August of 1945 was a definite turning point in the Pacific War of World . The outspoken Szilard was not involved in operational work on the bomb and General Groves kept him under surveillance but Met Lab director Arthur Compton found Szilard useful to have around. Responding to this threat, the United States placed an embargo on scrap metal, oil, and aviation fuel heading to Japan and froze Japanese assets in the United States. Included are documents on the early stages of the U.S. atomic bomb project, Army Air Force GeneralCurtis LeMays reporton the firebombing of Tokyo (March 1945), Secretary of War HenryStimsons requestsfor modification of unconditional surrender terms,Soviet documentsrelating to the events, excerpts from the Robert P. Meiklejohn diaries mentioned above, and selections from the diaries of Walter J. If there were, what were they and how plausible are they in retrospect? That evening army officers tried to seize the palace and find Hirohitos recording, but the coup failed. To produce material for any of those purposes required a capability to separate uranium isotopes in order to produce fissionable U-235. If you were President Truman in 1945, would you have dropped the bomb? [20], Harrison-Bundy Files relating to the Development of the Atomic Bomb, 1942-1946, microfilm publication M1108 (Washington, D.C.: National Archives and Records Administration, 1980), File 77: "Interim Committee - International Control.". Augusta, Truman learned about the atomic bombing of Hiroshima and announced it twice, first to those in the wardroom (socializing/dining area for commissioned officers), and then to the sailors mess. By contrast, Richard Frank takes note of the estimates depiction of the Japanese armys terms for peace: for surrender to be acceptable to the Japanese army it would be necessary for the military leaders to believe that it would not entail discrediting the warrior tradition and that it would permit the ultimate resurgence of a military in Japan. That, Frank argues, would have been unacceptable to any Allied policy maker.[33], Record Group 59, Decimal Files 1945-1949, 740.0011 PW (PE)/7-1645. It is commonly believed that the awesome devastation of the atomic bombs caused the Japanese government to capitulate. In any event, historians have used information from the diary to support various interpretations. Debates among the Japanese Late July/Early August 1945, IX. As the Russian invasion of Ukraine shows, nuclear threats are real, present, and dangerous. For Eisenhowers statements, seeCrusade in Europe(Garden City: Doubleday, 1948), 443, andMandate for Change(Garden City: Doubleday, 1963), 312-313. The History and Public Policy Programmakes public the primary source record of 20th and 21st century international history from repositories around the world, facilitates scholarship based on those records, and uses these materials to provide context for classroom, public, and policy debates on global affairs. Wait a moment and try again. At the time of the first report, various methods for producing a chain reaction were envisioned and money was being budgeted to try them out. What was at stake was the definition of the kokutai (national policy). This summary included intercepts of Japanese diplomatic reporting on the Soviet buildup in the Far East as well as a naval intelligence report on Anglo-American discussions of U.S. plans for the invasion of Japan. [74]. This. With Prime Minister Suzuki presiding, each of the ministers had a chance to state their views directly to Hirohito. To keep his pledge at Yalta to enter the war against Japan and to secure the territorial concessions promised at the conference (e.g., Soviet annexation of the Kuriles and southern Sakhalin and a Soviet naval base at Port Arthur, etc.) 8). A more recent collection of documents, along with a bibliography, narrative, and chronology, is Michael KortsThe Columbia Guide to Hiroshima and the Bomb(New York: Columbia University Press, 2007). The first paragraph mocks the Japanese press for exaggerating the aftereffects of the explosion, for giving in to popular rumor that takes press reports to absurdity. The Soviet report suggests that the exaggeration of the Japanese press stemmed from Japans attempt to save face in light of the defeat. The second, which hit Nagasaki on 9 August, killed around 50,000 people. In fact, after the bomb was dropped on Hiroshima on August 6, the Japanese military's Information Division, in charge of media control, intended to announce that the bomb was an atomic one. Thankfully, nuclear weapons have not been exploded in war since 1945, perhaps owing to the taboo against their use shaped by the dropping of the bombs on Japan. Hiroshima - view of Hiroshima Castle and surroundings; He believed that casualties would not be more than those produced by the battle for Luzon, some 31,000. [73] As it turned out, a few hours later, at 4:05 p.m., the White House received the Japanese surrender announcement. On the 70th anniversary of the bombing of Hiroshima on August 6, 1945, the National Security Archive updates its 2005 publication of the most comprehensive on-line collection of declassified U.S. government documents on the first use of the atomic bomb and the end of the war in the Pacific. On August 6, 1945, an atomic bomb was dropped on the people of Hiroshima. 25,000 more were injured. Despite the bombing of Hiroshima, the Soviet declaration of war, and growing worry about domestic instability, the Japanese cabinet (whose decisions required unanimity) could not form a consensus to accept the Potsdam Declaration. Most of these individuals were bureaucrats, which also explains the lack of scientific terms and technical observations on the effects of radiation. [56] Groves also provided the schedule for the delivery of the weapons: the components of the gun-type bomb to be used on Hiroshima had arrived on Tinian, while the parts of the second weapon to be dropped were leaving San Francisco. We will do our utmost to complete the war to the bitter end. That, Bix argues, represents a missed opportunity to end the war and spare the Japanese from continued U.S. aerial attacks. What Hirohito accepted, however, was a proposal by the extreme nationalist Kiichiro Hiranuma which drew upon prevailing understandings of the kokutai: the mythical notion that the emperor was a living god. For some historians, the urban fire-bombing strategy facilitated atomic targeting by creating a new moral context, in which earlier proscriptions against intentional targeting of civilians had eroded. The total area devastated by the atomic strike on Hiroshima is shown in the darkened area (within the circle) of the photo. By Marc Gallicchio. President Obama's visit to Hiroshima, nearly 71 years after it was destroyed by the first atomic bomb, inevitably raises once again the questions of why the United States dropped that bomb,. RG 77, Tinian Files, April-December 1945, box 21 (copies courtesy of Barton Bernstein). On the other hand much of the confirmed evidence Alperovitz presented was baffling. Tsar Bomba, the Largest Atomic Bomb in History The releasing of the atomic bombs to intimidate the Soviets in the years after World War Two is a valid claim because the . The US bombed Japan in 1945 to demonstrate its power to the USSR 576 words. Nevertheless, Anami argued, We are still left with some power to fight. Suzuki, who was working quietly with the peace party, declared that the Allied terms were acceptable because they gave a dim hope in the dark of preserving the emperor. 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. After a successful test of the weapon, Truman issued the Potsdam Declaration demanding the unconditional surrender of the Japanese government, warning of prompt and utter destruction. Eleven days later, on August 6, 1945, having received no reply, an American bomber called the Enola Gay left the Tinian Island in route toward Japan. The British National Archives, Records of the Foreign and Commonwealth Office, FO 800/461. [77]. Peter Grose,Gentleman Spy: The Life of Allen Dulles(Boston: Houghton Mifflin, 1994), 170-174, 248-249. See also Barton J. Bernstein, Looking Back: Gen. Marshall and the Atomic Bombing of Japanese Cities, Arms Control Today, November 2015. 75 years ago, in August 1945, the United States dropped the first and last atomic bombs used in warfare. This photo was taken from the Red Cross Hospital Building about one mile from the bomb burst. I.

Besides discussing programmatic matters (e.g., status of gaseous diffusion plants, heavy water production for reactors, and staffing at Las Alamos), the participants agreed that the first use could be Japanese naval forces concentrated at Truk Harbor, an atoll in the Caroline Islands. General Douglas MacArthur had been slated as commander for military operations against Japans mainland, this letter to Truman from Forrestal shows that the latter believed that the matter was not settled. Togos proposal would have been generally consistent with a constitutional monarchy because it defined the kokutai narrowly as the emperor and the imperial household. In his 1948 memoirs (further amplified in his 1963 memoirs), Eisenhower claimed that he had expressed the hope [to Stimson] that we would never have to use such a thing against an enemy because I disliked seeing the United States take the lead in introducing into war something as horrible and destructive as this new weapon was described to be. That language may reflect the underlying thinking behind Eisenhowers statement during the dinner party, but whether Eisenhower used such language when speaking with Stimson has been a matter of controversy. [71]. 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? The ban on the public use of the phrase was officially lifted when the war ended on August 15, which prompted Hiroshimas local newspaper, the Chgoku Shimbun, to print a few photos of the destroyed city on August 23. As he argued in this memorandum to President Truman, failure on our part to clarify our intentions on the status of the emperor will insure prolongation of the war and cost a large number of human lives. Documents like this have played a role in arguments developed by Alperovitz that Truman and his advisers had alternatives to using the bomb such as modifying unconditional surrender and that anti-Soviet considerations weighed most heavily in their thinking. According to Hasegawa, Hirohito had become convinced that the preservation of the monarchy was at stake. Was The Atomic Bomb Used To Stop Soviet Expansion? On August 6, 1945, the United States dropped an atomic bomb on Hiroshima. Truth or Consequences - Los Angeles Times - News from California, the For further consideration of Tokyo and more likely targets at the time, see Alex Wellerstein, Neglected Niigata,Restricted Data: The Nuclear Secrecy Blog, 9 October 2015. The First Nuclear Strikes and their Impact, XI. Open Document. The war was finally over. [14]. And on Aug. 6, a bomb would fall on Hiroshima, ultimately killing an. Stimson had in mind a carefully timed warning delivered before the invasion of Japan. The diary entries cover July 16, 17, 18, 20, 25, 26, and 30 and include Trumans thinking about a number of issues and developments, including his reactions to Churchill and Stalin, the atomic bomb and how it should be targeted, the possible impact of the bomb and a Soviet declaration of war on Japan, and his decision to tell Stalin about the bomb. The Japanese Search for Soviet Mediation, VII. [39], The last item discusses Japanese contacts with representatives of the Office of Strategic Services (OSS) in Switzerland. This update presents previously unpublished material and translations of difficult-to-find records. 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. When he learned of the atomic bombing from the Domei News Agency, Togo believed that it was time to give up and advised the cabinet that the atomic attack provided the occasion for Japan to surrender on the basis of the Potsdam Declaration. In what Stimson called the letter of an honest man, Oswald C. Brewster sent President Truman a profound analysis of the danger and unfeasibility of a U.S. atomic monopoly.
