 Wars have often been provoked by international incidents, and diplomatic efforts to prevent international incidents from growing into full-scale armed conflicts often have been unsuccessful.In the aftermath of the First World War, the League of Nations was established to help nations who were parties to an international incident achieve a solution to the incident through diplomatic means.Initially, the League of Nations had some success in working to find diplomatic solutions, however the failure of the League of Nations to prevent World War II resulted in the disbandment of the League of Nations in favor of the United Nations.
