But it was the opposite, Truman caused the Cold War the moment he dropped the atomic bomb. Melvyn P. Leffler, Adherence to Agreements: Yalta and the Experiences of the Early Cold War,International Security11 (1986): 107; Holloway, Barbarossa and the Bomb, 65. The cost of invasion, they knew, would be high. On October 30, 1961, the Soviet Union tested the largest nuclear device ever created. Frank and Hasegawa divide over the impact of the Soviet declaration of war, with Frank declaring that the Soviet intervention was significant but not decisive and Hasegawa arguing that the two atomic bombs were not sufficient to change the direction of Japanese diplomacy. Compton raised doubts about the recommendations but urged Stimson to study the report. 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. On August 6, 1945, the United States dropped an atomic bomb on Hiroshima. [23] It is possible that Truman was informed of such discussions and their conclusions, although he clung to a belief that the prospective targets were strictly military. [34], On the eve of the Potsdam conference, Leo Szilard circulated a petition as part of a final effort to discourage military use of the bomb. 2023 The Wilson Center. Another column was striking south from the Soviet border toward Hailar. The killing of workers in the urban-industrial sector was one of the explicit goals of the air campaign against Japanese cities.

According to Merkulov, two fissile materials were being produced: element-49 (plutonium), and U-235; the test device was fueled by plutonium. In keeping with General Groves emphasis on compartmentalization, the Manhattan Project experts on the effects of radiation on human biology were at the MetLab and other offices and had no interaction with the production and targeting units. (Photo from U.S. National Archives, RG 77-AEC), An overview of the destruction of Hiroshima [undated, circa August-September 1945]. The First Nuclear Strikes and their Impact, XI. Meiklejohn recounted Harrimans visit in early October 1945 to the Frankfurt-area residence of General Dwight Eisenhower, who was finishing up his service as Commanding General, U.S. Army, European Theater. The documents cover multiple aspects of the bombings and their context. The president, however, wrote in long-hand a text that that might approximate what he said that evening. [58]. The embassy teams included GRU members Mikhail Ivanov and German Sergeev in August, and TASS correspondent Anatoliy Varshavskiy, former acting military attach Mikhail Romanov, and Naval apparatus employee Sergey Kikenin in September. 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. Read more, The Cold War International History Project supports the full and prompt release of historical materials by governments on all sides of the Cold War. The documents introduced here were published in Russian for the first time in 1990, and the English version was included in an issue of the Soviet journal International Affairs (1990, no. The notion that the atomic bombs caused . When the atomic bomb was dropped, I felt: "This is terrible." Immediately thereafter, it was reported Soviet Russia entered the war. It is 28 inches in diameter and 120 inches long. The museum has justfinished a massive renovation of the museum and its exhibitions, the first major renovation in more than 20 years and the largest since the museum opened its doors in 1957. For reviews of the controversy, see Barton J. Bernstein, The Struggle Over History: Defining the Hiroshima Narrative, ibid., 128-256, and Charles T. OReilly and William A. Rooney,The Enola Gay and The Smithsonian(Jefferson, NC: McFarland and Company, 2005). This photo was taken from the Red Cross Hospital Building about one mile from the bomb burst. 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. Lower image - August 11, 1945, photo by 6th Photo Reconnaissance Group At the beginning of the discussion, Eisenhower made a significant statement: he mentioned how he had hoped that the war might have ended without our having to use the atomic bomb. The general implication was that prior to Hiroshima-Nagasaki, he had wanted to avoid using the bomb. The United States, then, dropped the bombs to end the war that Japan had unleashed in Asia in 1931 and extended to the United States at Pearl Harborand thereby probably avoided an invasion that. Henry L. Stimson Papers (MS 465), Sterling Library, Yale University (reel 113) (microfilm at Library of Congress), Still interested in trying to find ways to warn Japan into surrender, this represents an attempt by Stimson before the Potsdam conference, to persuade Truman and Byrnes to agree to issue warnings to Japan prior to the use of the bomb. 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. Marshall was not sure whether that was so although Stimson privately believed that the atomic bomb would provide enough to force surrender (see entry for July 23). Documents 77A-B: The First Japanese Offer Intercepted. By 1937 Japan controlled large sections of China and accusations of war crimes against the Chinese people became commonplace. General George C. Marshall is the only high-level official whose contemporaneous (pre-Hiroshima) doubts about using the weapons against cities are on record. This 10 July 1945 letter from NKVD director V. N. Merkulov to Beria is an example of Soviet efforts to collect inside information on the Manhattan Project, although not all the detail was accurate. 24, tab D, Soon after he was sworn in as president following President Roosevelts death, Harry Truman learned about the top secret Manhattan Projectfrom briefingsbySecretary of War Stimson and Manhattan Project chief General Groves (who went through the back door to escape the watchful press). Martin Sherwin has argued that the Franck committee shared an important assumption with Truman et al.--that an atomic attack against Japan would `shock the Russians--but drew entirely different conclusions about the import of such a shock. On August 6th, 1945 at 8:15 A.M. the U.S. dropped an atomic bomb over the Japanese city of Hiroshima. What did senior officials know about the effects of atomic bombs before they were first used. Alperovitz and Sherwin have argued that Truman made a real decision to use the bomb on Japan by choosing between various forms of diplomacy and warfare. In contrast, Bernstein found that Truman never questioned [the] assumption that the bomb would and should be used. In this context, Naryshkins words gain a particular nuance: the anniversaries of Hiroshima and Nagasaki were an excellent opportunity for Moscow to revive its relationship with Tokyo, which irritated US officials at a time when the United States sought a united front with its ally in light of Russias increasingly aggressive behavior. Those and other questions will be subjects of discussion well into the indefinite future. 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. 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. The Japanese Surrender in World War II. 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. were the atomic strikes necessary primarily to avert an invasion of Japan in November 1945? 24 Jun . Small; Normal; . Japans cultural capital, Kyoto, would not stay on the list. While Army Minister Anami tacitly threatened a coup (civil war), the emperor accepted the majority view that the reply to the Potsdam declaration should include only one condition not the four urged by Big Six. Nevertheless, the condition that Hirohito accepted was not the one that foreign minister Togo had brought to the conference. On August 9th, 1945, Truman declared that the use of the A-bomb had saved THOUSANDS of American lives. Leaflets dropped on cities in Japan warning civilians about the atomic bomb, dropped c. August 6, 1945. After considerable pressure from Harriman, the Soviets signed off on the reply but not before tensions surfaced over the control of Japan--whether Moscow would have a Supreme Commander there as well. [13] According to the Foreword, the purpose of the raid, which dropped 1,665 tons of incendiary bombs, was to destroy industrial and strategic targets not to bomb indiscriminately civilian populations. Air Force planners, however, did not distinguish civilian workers from the industrial and strategic structures that they were trying to destroy.

Conant: Harvard to Hiroshima and the Making of the Nuclear Age(Stanford, Stanford University Press, 1995), 140-154. However, the Department of the Interior opposed the disclosure of the nature of the weapon. Besides material from the files of the Manhattan Project, this collection includes formerly Top Secret Ultra summaries and translations of Japanese diplomatic cable traffic intercepted under the Magic program. Contributors to the historical controversy have deployed the documents selected here to support their arguments about the first use of nuclear weapons and the end of World War II. [40]. They caused terrible human losses and destruction at the time and more deaths and sickness in the years ahead from the radiation effects. The entry from Meiklejohns diary does not prove or disprove Eisenhowers recollection, but it does confirm that he had doubts which he expressed only a few months after the bombings. Restricted Data: The Nuclear Secrecy Blog. In Japan and elsewhere around the world, each anniversary is observed with great solemnity. The nuclear age had truly begun with the first military use of atomic weapons. Moreover, to shed light on the considerations that induced Japans surrender, this briefing book includes new translations of Japanese primary sources on crucial events, including accounts of the conferences on August 9 and 14, where Emperor Hirohito made decisions to accept Allied terms of surrender.
