This is an international organization- made up of most every country- created following world war ii to provide a way to negotiate disputes.

The correct answer is the United Nations.

This organization was founded after World War II as a means to keep international peace and solve problems. This also became the organization where individuals who committed crimes like genocide would be brought to be punished. This included individuals who took part in the Holocaust during World War II, the Rwandan genocide of the 1990s, and the Bosnian genocide of the 1990's.
