Hearings held in Nuremberg and Tokyo established that aggression is the ‘supreme international crime’—one for which leaders from Nazi Germany and imperial Japan were sentenced to death.
The Nuremberg Tribunal’s judgment was very clear on this point: ‘To initiate a war of aggression is not only an international crime; it is the supreme international crime, differing only from other war crimes in that it contains within itself the accumulated evil of the whole.’ Since then, the international order has rested on the territorial integrity of states. To challenge this core principle with a violent act of aggression—the supreme international crime—is to put the entire world at risk of sinking into disorder, chaos and war.
