The Decision to Use the Atomic Bomb (Reading Notes, Book I, Chapters 1-9): I. Book I: The Decision i. Chapter One: The Trajectory of Japan’s Decline (p. 17)- In June of 1945, as the end of WWII approached, how did Japanese military leaders assess their overall situation, especially after Okinawa fell to the Americans? [Japan and everyone else knew they were screwed and many Japanese intellectuals suggested peace negotiations as a way to preserve their countries integrity.] 1. Robert J.C. Butow- “…the scales of war had been tipped so steeply against the Japanese that no counterweight at their disposal could possibly have balanced them.” (p. 17) a. Japan’s first line of defense, Germany, was facing imminent destruction. 2. The Pacific front had initially moved relatively slowly. 3. The fall of Saipan, Tinian, and Guam provided bases which brought Japan into better B-29 bombing range. 4. General George C. Kennedy, Commander of Air Forces- “Jap is not going to last much longer. His sea power is badly depleted…he has lost his element, flight, squadron and group leaders and his hastily trained replacements.” (p. 18) 5. [March 9-10, 1945] Firebombing of Tokyo: Military and human catastrophe. 84,000 casualties. 6. [March 1945] Collapse of Iwo Jima: allowed for heavy bombing missions. 7. “Clearly, Japan was defeated and preparing to surrender before the atomic bomb was used.” a. The U.S. had an understanding of this concept. 8. Suzuki Kantaro: [Took office as Prime Minister 04/07/1945] Contributed to final peace negotiations with Allied forces. Called two imperial conferences which helped resolve the split within the Japanese Imperial Cabinet over the Potsdam Declaration. Outlined the terms to Emperor Hirohito who had already agreed to unconditional surrender. a. Government Assessment by Office of Strategic Services- “Suzuki’s appointment has all the appearances of a desperate stop-gap arrangement, an effort to by-pass these extremists an yet provided a new political alignment which can lay the basis for peace negotiations if possible.” (p. 19) 9. Japan depended more on imports than even the U.K. a. “The continued heavy destruction of machinery and equipment will make it impossible for Japan to replace losses with her existing or potential machine tool and heavy equipment industry.” (p. 19) b. The Japanese under these conditions would continue in the war but would weaken progressively. 10. U.S. had long broken Japanese intelligence codes and were regularly reading high level cable and radio messages. 11. Neutrality Pact: plunged Japanese into despair. 12. Soviet Foreign Minister, Vyacheslav M. Molotov- “Since Japan is facing a grave situation which permits no delay it is urgently necessary that we should sound out Russia’s real intentions *toward Japan+ and exhaust all possibilities of bringing about a new turn in the situation.” (p. 20) 13. U.S. very aware of importance of Soviet announcement. a. “If at any time the U.S.S.R. should enter the war, all Japanese will realize that absolute defeat is inevitable.” (p. 20) 14. Major General Clayton Bissell- “The Japanese have been brought to a cold realization of their isolated position by the surrender of Germany, and evidence indicates that they are appalled by the destruction wrought on German cities.” 15. In the same memorandum Bissell recommended an immediate surrender ultimatum. 16. Appraisal presented at meeting of Supreme Council in Direction of the War for Japanese Military: a. The people are losing confidence in their leaders. b. There is a deterioration of public moral. c. Leading intellectuals advocate for peace negotiations. d.

Japan’s navy is nearly destroyed. i. Vulnerable to blockade to deprive them of food and supplies. c. Japan vulnerable to air attack to cities, industry, and food sources. d. China and the ominous threat of Russia. e. U.S. has inexhaustible and untouched industrial resources. 18. Combined U.S.-British Intelligence Committee Report- “The increasing effects of sea blockade and the cumulative devastation wrought by strategic bombing, which has already rendered millions homeless and has destroyed from 25% to 50% of the built up area of Japan’s most important cities. 19. Japan was in such a bad way it began processing acorns as a substitute for rice. ii. Chapter Two: General Efforts to End the War (p. 23)-In July 1945, what was the single key Japanese demand put forward in various diplomatic feelers and informal discussion? 1. American cryptographers intercepted messages that suggested Japan was seeking to end the war. 2. Shigemitsu’s instructions imply that he has in mind a move by Russia to begin peace talks with the Americans. 3. Shigemitsu’s assessment: U.S. was already in Japanese territorial waters and had superiority in sea and air attacks. 4.

[May 7, 1945] OSS reports- “the Japanese are ready to cease hostilities…” (p. 26) 7. Fujimara (principal Japanese Naval Representative in Europe): navy circles particularly stress the necessity of preserving the Emperor in order to avoid Communism and chaos. 8. Major General Onodera: Emperor must be maintained after Japanese surrender. 9. OSS Representative Allen Dulles: “the only condition on which Japan would insist with respect to surrender would be some consideration for the Japanese Imperial family.” (p. 27) 10. Meetings with important Japanese representatives indicated Japan’s deteriorating internal state. 11. “His Majesty the Emperor, mindful of the fact the present war daily brings greater evil and sacrifice upon the peoples of all belligerent powers, desires form his hear that it may be quickly terminated.” (p. 28) b. Part I: Unconditional Surrender i. Chapter Three: April-May 1945 (p. 33)- When Germany surrendered on May 8, 1945, President Truman issued a statement defining the meaning of unconditional surrender for Japan. What was it? 1. James F. Byrnes- “Had the Japanese Government listened to [Ambassador to the Soviet Union] Sato and surrendered unconditionally, it would not have been necessary to drop the atomic bomb.” 2. Truman was urged to clarify terms of Japanese surrender by all those who had regular access to the president. 3. Truman generally saw little difficult to modifying the surrender terms to include a stipulation allowing for the maintenance of the Emperor as a figure head. a. After dropping the atomic bomb Truman allowed the Emperor to stay. 4. “The Imperial Family is the fountain source of the Japanese nation.” (p. 36) 5. U.S. demand for unconditional surrender directly threatens the status of the Emperor and the central tenets of Japanese culture. 6. There were three key points in relation to the maintenance of the Emperor: a. Japanese would not surrender if the Emperor was removed from his throne or harmed in any way. b. If the previous was not assured the Japanese would most likely fight until the last man. c. The Emperor would play a key role in maintaining internal order in post-war Japan. 7. In the FDR days, there was a conditional, “unconditional” surrender for Italy. 8. Initially Truman’s moved indicated he was in the similar mindset to FDR, but upon taking office he returned to the traditional. a. *April 16, 1945+ “Our demand has been and it remains- unconditional surrender. We will not traffic with the breaker of the peace on the terms of peace.” (p. 39) 9. Truman did not hesitate to renegotiate after dropping the atomic bomb. 10. *May 8, 1945+ President carefully defined “unconditional surrender”. a. Means end of war. b. Means termination of the influence of the military leaders who brought Japan to present disaster. c. Does not mean extermination or enslavement of Japanese people. 11. Navy Captain Ellis Zacharias: in charge of propaganda policy for the Far East. 12. “The invasion of Japan is considered to be the most suitable strategy for to accomplish unconditional surrender or ultimate defeat.” (p. 42) 13.

The sense shown in the Russo-Japanese war (made peace before being hit with full might of Russia.) d. Fear of complete Japanese destruction. e. Large middle class in Japan who are liberal minded and are the only hope of a stable and progressive government. ii. Chapter Four: To June 18, 1945 (p. 47)- Joseph Grew was Acting Secretary of State in May of 1945. What did he advocate regarding the definition of unconditional surrender? What was S-1 and where did it fit in the picture? What three key policy questions emerge at this time? 1. [May 28, 1945] Grew reviewed surrender formula with President Truman. 2. The next phase of policy concerning “unconditional surrender”: a. Why was developing course of action abandoned by the President? b. Who was the central presidential advisor on the matter? c. Why was the emerging policy thrust not only abandoned but publically reversed? 3. Grew’s Memoir *1952+: “The purpose of the meeting (with top-level military individuals [May 29, 1945]) was to discuss whether the president should comment on the intentions of determining Japan’s future political structure. a. Marshall, Stimson, Forrestal advised against it. 4. General Marshall thought that the atomic bombs should be uses first at naval installations, then industrial areas from which people would be evacuated before the drop. a. Advocated for a clear warning to Japanese people’s to evacuate the cities/population centers being targeted. 5. Stalin- “If we stick to unconditional surrender, the Japs will not give up and we will have to destroy them as we did Germany.” 6. State Department analysis of Hoover’s memorandum states that failure to clarify intentions or threat of removal an destruction of the Emperor will result in prolongation of the war and loss of human life. 7. There was concern that the Japanese would offer a conditional surrender that would be well received by the U.S. public. 8. Grew- “…I think it will be a matter of plain common sense to give the Japanese a clearer idea of what we mean by unconditional surrender.” (p. 59) 9. Discussion of the announcements and warnings was postponed until the Big Three Meeting. iii. Chapter Five: June 18, 1945 (p. 62)- What were Truman’s key advisors recommending regarding the timing of a surrender formula, and which adviser most likely influenced Truman to reverse the thrust of his May 8 statement suggesting openness to some modification of the demand for unconditional surrender? 1. Why did Truman choose to wait until the Big Three meeting rather than act on the dramatic occasion of the fall of Okinawa- as Grew, Stettinius, and, most significantly, the Joint Chiefs of Staff recommended? a. Why the thinking of the president’s top military advisors-who also knew about the bomb and the likelihood of Russian help- was rejected? b. It is clear that not Stettinius, Grew, Stimson, or Marshall counseled the president on the matter. 2. Truman main emphasis was minimizing American casualties. 3. Truman’s June 18 meeting with Joint Chiefs of Staff was narrowly focused on military issues. a. Ending the war through alternative means was also raised sat several points. 4. “The President asked if the invasion of Japan by white men would not have the effect of more closely uniting the Japanese.” (p. 64) 5. The president’s chief of staff also pressed the political issues: a. “He feared no menace from Japan in the foreseeable future, even if we are unsuccessful in forcing unconditional surrender. He did not think this was at all necessary.” (p. 65) 6. Leahy: “Every living person in Japan would prefer to die fighting rather than accept military defeat…” (p. 65) 7. Truman never indicated in public statements that he desired a congressional lead on matters. 8.
