In the immediate aftermath of the bomb, the allied occupation authorities banned all mention of radiation poisoning and insisted that people had been killed or injured only by the bomb's blast. It was the first big lie.
The atomic bombing of Hiroshima and Nagasaki was a criminal act on an epic scale. It was premeditated mass murder that unleashed a weapon of intrinsic criminality.
The most enduring lie is that the atomic bomb was dropped to end the war in the Pacific and save lives. "Even without the atomic bombing attacks," concluded the United States Strategic Bombing Survey of 1946, "air supremacy over Japan could have exerted sufficient pressure to bring about unconditional surrender and obviate the need for invasion. Based on a detailed investigation of all the facts, and supported by the testimony of the surviving Japanese leaders involved, it is the Survey's opinion that ... Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war and even if no invasion had been planned or contemplated."
