"The problem the Great Powers now faced (after world war II) was how to create a process that the world would consider something more than vengeance masquerading as righteousness, something more than “victors’ justice.” The solution was to demonstrate that their prosecutions had a basis in the Geneva Conventions and other international treaties -- in, that is, the already existing laws of war. In the process of designing those prosecutions, they consolidated and advanced the meaning and power of international law itself, a concept particularly needed in a postwar world of atomic weapons and a looming U.S.-Soviet conflict. Three-quarters of a century and many wars and weapon systems later, enforceable international law still remains humanity’s best hope for adjudicating past war crimes and preventing future ones -- but only if great nations like the United States do not declare themselves exceptions to the rule of law."
