9 Walter Trohan, a reporter for the Chicago Tribune, reported that two days before President Roosevelt left for the Yalta conference with Winston Churchill and Joseph Stalin in early February 1945, he was shown a forty-page memorandum drafted by General MacArthur outlining a Japanese offer for surrender almost identical with the terms later concluded by President Truman. Trohan related that he was given a copy of this communication by Admiral William Leahy who swore him to secrecy with the pledge not to release the story until the war was over. Trohan honored his pledge and reported his story in the Chicago Tribune and the Washington Times-Herald on August 19, 1945. Cited in John J.

In early May 1946, while on a tour of the Pacific, former President Herbert Hoover met with General Douglas MacArthur alone for several hours. Hoover recalled: “I told MacArthur of my memorandum of mid-May 1945 to Truman, that peace could be had with Japan by which our major objectives would be accomplished. MacArthur said that was correct and that we would have avoided all of the losses, the atomic bomb, and the entry of Russia into Manchuria.” Herbert Hoover Diary, 1946 Journey, May 4, 5, 6, 1946, Post-Presidential Papers, Herbert Hoover Presidential Library.

At the request of the U.S., Soviet leader Joseph Stalin agreed to enter the war against Japan three months after the end of the war in Europe (May 8). The Soviet Union did so at the appointed hour, sending a massive invasion force to take over the Japanese puppet state of Manchukuo (Manchuria). Over the next few weeks, almost 600,000 Japanese soldiers surrendered to Soviet forces in Manchuria, Sakhalin and the Kurile chain.

The historian Tsuyoshi Hasegawa, in Racing the Enemy: Stalin, Truman, and the Surrender of Japan (Cambridge: Belknap Press, 2005), makes a strong case, based on careful reading of Japanese documents, that Soviet entry into the war rather than the dropping of the two nuclear bombs was decisive in compelling Japan's surrender. He did not convince reviewer Marc Gallicchio, however, who wrote, “It seems safer to conclude that the nuclear bombs and the impact of the Soviet invasion were too closely intertwined for historians to disentangle them as neatly as Hasegawa implies.” Marc Gallicchio, “Review Works: Racing the Enemy: Stalin, Truman, and the Surrender of Japan by Tsuyoshi Hasegawa,” Journal of Cold War Studies, Vol, 9, No. 4 (Fall 2007), 170.
