Now I have become Death, the destroyer of worlds

With regards to Jesus (The Apologist) Diaz over at Gizmodo who found this:

The Japanese resolve to fight had been seriously hampered in the preceding months. Their losses at Iwo Jima and Okinawa had been staggering. Their navy had ceased to exist as an effective fighting force and the air corps had been decimated. American B-29’s made bombing runs over military targets on the Japanese mainland an integral part of their air campaign. Japan’s lack of air power hindered their ability to fight. The imprecision of bombing and the use of devastating city bombing in Europe eventually swayed United States Pacific theater military leaders to authorize bombing of Japanese mainland cities. Tokyo, Nagoya, Osaka, and Kobe all were decimated by incendiary and other bombs. In all, hundreds of thousands of civilians were killed in these air strikes meant to deter the resolve of the Japanese people. Yet, Japanese resolve stayed strong and the idea of a bloody "house to house" invasion of the Japanese mainland would produce thousands more American and Allied casualties. The Allies in late July 1945 declared at Potsdam that the Japanese must unconditionally surrender.

After Japanese leaders flatly rejected the Potsdam Declaration, President Truman authorized use of the atomic bomb anytime after August 3, 1945. (From the Truman Library)

On August 6, 1945, the cumulated works of the Manhattan Project came to fruition in the first release of a nuclear device in time of war. Within seconds of the impact and estimated 70,000 Japanese inhabitants of Hiroshima were killed. Three days later the second, and last nuclear attack ever was completed on Nagasaki.

Shortly thereafter Emperor Hirohito made the following statement:

Moreover, the enemy now possesses a new and terrible weapon with the power to destroy many innocent lives and do incalculable damage. Should we continue to fight, not only would it result in an ultimate collapse and obliteration of the Japanese nation, but also it would lead to the total extinction of human civilization.

Such being the case, how are We to save the millions of Our subjects, or to atone Ourselves before the hallowed spirits of Our Imperial Ancestors? This is the reason why We have ordered the acceptance of the provisions of the Joint Declaration of the Powers.

Which led to this:

The Japanese unconditional surrender on September 2, 1945. Which ultimately saved millions of lives because the Japanese culture would have produced a fight to the death for every person, military or civilian alike had Operation Downfall been commenced.

A tough call, but one that was made in the best interests of America. Thank you President Truman.
