In the weeks after Japan finally surrendered to the Allies to end WWII, the world turned to the question of how to move on from years of carnage and destruction. For Harry Truman, Douglas MacArthur, Chiang Kai-shek, and their fellow victors, the question of justice seemed clear: Japan's militaristic leaders needed to be tried and punished. For the Allied powers, the trial was an opportunity to render judgment on their vanquished foes, but also to create a legal framework to prosecute war crimes and prohibit the use of aggressive war, building a more peaceful world under international law and American hegemony. For the Japanese leaders on trial, it was their chance to argue that their war had been waged to liberate Asia from Western imperialism and that the court was victors' justice. This magnificent history is the product of a decade of research and writing.
