不戦条約
The 1928 Kellogg–Briand Pact was concluded outside the League of Nations and remains in effect. One month following its conclusion, a similar agreement, General Act for the Pacific Settlement of International Disputes, was concluded in Geneva, which obliged its signatory parties to establish conciliation commissions in any case of dispute. The pact's central provisions renouncing the use of war, and promoting peaceful settlement of disputes and the use of collective force to prevent aggression, were incorporated into the United Nations Charter and other treaties. Although civil wars continued, wars between established states have been rare since 1945, with a few exceptions in the Middle East.
