The Real Reason America Used Nuclear Weapons Against Japan. And it Was Not To End the War Or Save Lives..........................I proposed to Secretary Forrestal that the weapon should be demonstrated before it was used. Primarily it was because it was clear to a number of people, myself among them, that the war was very nearly over. The Japanese were nearly ready to capitulate… My proposal to the Secretary was that the weapon should be demonstrated over some area accessible to Japanese observers and where its effects would be dramatic. I remember suggesting that a satisfactory place for such a demonstration would be a large forest of cryptomeria trees not far from Tokyo. The cryptomeria tree is the Japanese version of our redwood… I anticipated that a bomb detonated at a suitable height above such a forest… would lay the trees out in windrows from the center of the explosion in all directions as though they were matchsticks, and, of course, set them afire in the center. It seemed to me that a demonstration of this sort would prove to the Japanese that we could destroy any of their cities at will…Secretary Forrestal agreed wholeheartedly with the recommendation…It seemed to me that such a weapon was not necessary to bring the war to a successful conclusion, that once used it would find its way into the armaments of the world…General George Marshall agreed:
Contemporary documents show that Marshall felt “these weapons might first be used against straight military objectives such as a large naval installation and then if no complete result was derived from the effect of that, he thought we ought to designate a number of large manufacturing areas from which the people would be warned to leave–telling the Japanese that we intend to destroy such centers….”As the document concerning Marshall’s views suggests, the question of whether the use of the atomic bomb was justified turns … on whether the bombs had to be used against a largely civilian target rather than a strictly military target—which, in fact, was the explicit choice since although there were Japanese troops in the cities, neither Hiroshima nor Nagasaki was deemed militarily vital by U.S. planners. (This is one of the reasons neither had been heavily bombed up to this point in the war.) Moreover, targeting [at Hiroshima and Nagasaki] was aimed explicitly on non-military facilities surrounded by workers’ homes.
Historians Agree that the Bomb Wasn’t Needed
Historians agree that nuclear weapons did not need to be used to stop the war or save lives.As historian Doug Long notes:U.S. Nuclear Regulatory Commission historian J. Samuel Walker has studied the history of research on the decision to use nuclear weapons on Japan. In his conclusion he writes, “The consensus among scholars is that the bomb was not needed to avoid an invasion of Japan and to end the war within a relatively short time. It is clear that alternatives to the bomb existed and that Truman and his advisors knew it.” (J. Samuel Walker, The Decision to Use the Bomb: A Historiographical Update, Diplomatic History, Winter 1990, pg. 110).
Politicians Agreed........Many high-level politicians agreed. For example, Herbert Hoover said (pg. 142): The Japanese were prepared to negotiate all the way from February 1945…up to and before the time the atomic bombs were dropped; …if such leads had been followed up, there would have been no occasion to drop the [atomic] bombs.
Under Secretary of State Joseph Grew noted (pg. 29-32):In the light of available evidence I myself and others felt that if such a categorical statement about the [retention of the] dynasty had been issued in May, 1945, the surrender-minded elements in the [Japanese] Government might well have been afforded by such a statement a valid reason and the necessary strength to come to an early clearcut decision.If surrender could have been brought about in May, 1945, or even in June or July, before the entrance of Soviet Russia into the [Pacific] war and the use of the atomic bomb, the world would have been the gainer.
Why Then Were Atom Bombs Dropped on Japan?
If dropping nuclear bombs was unnecessary to end the war or to save lives, why was the decision to drop them made? Especially over the objections of so many top military and political figures? One theory is that scientists like to play with their toys:On September 9, 1945, Admiral William F. Halsey, commander of the Third Fleet, was publicly quoted extensively as stating that the atomic bomb was used because the scientists had a “toy and they wanted to try it out . . . .” He further stated, “The first atomic bomb was an unnecessary experiment . . . . It was a mistake to ever drop it.”
However, most of the Manhattan Project scientists who developed the atom bomb were opposed to using it on Japan.
Albert Einstein – an important catalyst for the development of the atom bomb (but not directly connected with the Manhattan Project) – said differently:“A great majority of scientists were opposed to the sudden employment of the atom bomb.” In Einstein’s judgment, the dropping of the bomb was a political – diplomatic decision rather than a military or scientific decision.
Indeed, some of the Manhattan Project scientists wrote directly to the secretary of defense in 1945 to try to dissuade him from dropping the bomb: We believe that these considerations make the use of nuclear bombs for an early, unannounced attack against Japan inadvisable. If the United States would be the first to release this new means of indiscriminate destruction upon mankind, she would sacrifice public support throughout the world, precipitate the race of armaments, and prejudice the possibility of reaching an international agreement on the future control of such weapons.

The scientists questioned the ability of destroying Japanese cities with atomic bombs to bring surrender when destroying Japanese cities with conventional bombs had not done so, and – like some of the military officers quoted above – recommended a demonstration of the atomic bomb for Japan in an unpopulated area.
The Real Explanation?
History.com notes:
In the years since the two atomic bombs were dropped on Japan, a number of historians have suggested that the weapons had a two-pronged objective …. It has been suggested that the second objective was to demonstrate the new weapon of mass destruction to the Soviet Union. By August 1945, relations between the Soviet Union and the United States had deteriorated badly. The Potsdam Conference between U.S. President Harry S. Truman, Russian leader Joseph Stalin, and Winston Churchill (before being replaced by Clement Attlee) ended just four days before the bombing of Hiroshima. The meeting was marked by recriminations and suspicion between the Americans and Soviets. Russian armies were occupying most of Eastern Europe. Truman and many of his advisers hoped that the U.S. atomic monopoly might offer diplomatic leverage with the Soviets. In this fashion, the dropping of the atomic bomb on Japan can be seen as the first shot of the Cold War.
New Scientist reported in 2005:The US decision to drop atomic bombs on Hiroshima and Nagasaki in 1945 was meant to kick-start the Cold War rather than end the Second World War, according to two nuclear historians who say they have new evidence backing the controversial theory.Causing a fission reaction in several kilograms of uranium and plutonium and killing over 200,000 people 60 years ago was done more to impress the Soviet Union than to cow Japan, they say. And the US President who took the decision, Harry Truman, was culpable, they add.“He knew he was beginning the process of annihilation of the species,” says Peter Kuznick, director of the Nuclear Studies Institute at American University in Washington DC, US. “It was not just a war crime; it was a crime against humanity.”
[The conventional explanation of using the bombs to end the war and save lives] is disputed by Kuznick and Mark Selden, a historian from Cornell University in Ithaca, New York, US.New studies of the US, Japanese and Soviet diplomatic archives suggest that Truman’s main motive was to limit Soviet expansion in Asia, Kuznick claims. Japan surrendered because the Soviet Union began an invasion a few days after the Hiroshima bombing, not because of the atomic bombs themselves, he says.According to an account by Walter Brown, assistant to then-US secretary of state James Byrnes, Truman agreed at a meeting three days before the bomb was dropped on Hiroshima that Japan was “looking for peace”. Truman was told by his army generals, Douglas Macarthur and Dwight Eisenhower, and his naval chief of staff, William Leahy, that there was no military need to use the bomb.“Impressing Russia was more important than ending the war in Japan,” says Selden.
