Japanese war crimes
The U.S. officially classified all 3,649 military and civilian casualties and destruction of military property at Pearl Harbor as non-combatants as there was no state of war between the U.S. and Japan when the attack occurred. Joseph B. Keenan, the chief prosecutor in the Tokyo Trials, says that the attack on Pearl Harbor not only happened without a declaration of war but was also a treacherous and deceitful act. In fact, Japan and the U.S. were still negotiating for a possible peace agreement which kept U.S. officials very distracted when Japanese planes bombed Pearl Harbor. Keenan explained the definition of a war of aggression and the criminality of the attack on Pearl Harbor:
Gerald Nye
The day of the Japanese bombing of Pearl Harbor on December 7, 1941, Nye attended an America First meeting in Pittsburgh. Before his speech a reporter for the "Pittsburgh Post-Gazette" told him about the attack, but Nye was skeptical and did not mention the news to the audience. The reporter passed him a note during the speech stating that Japan had declared war; Nye read it but continued speaking. He only announced the attack at the end of his one-hour speech, stating that he had received "the worst news that I have encountered in the last 20 years". However, the next day Nye joined the rest of the Senate in voting for a unanimous declaration of war.
