"Following the horrific destruction left in the wake of World War II, the United Nations in its seminal and founding document, the Charter of the United Nations, set out to prevent future wars among member nations. The Charter’s admonition against war was also voiced in the lessons learned from the Nuremberg trials of Nazi war criminals in its condemnation of war: “starting or waging a war against a territorial integrity, political independence or sovereignty of a state, or violation of international treaties or agreements.” are crimes against peace and “makes all war crimes possible.”"
