What were the steps taken to avoid world war 2?

To avoid World War II, several diplomatic efforts were made, including the Treaty of Versailles' reassessment and the establishment of the League of Nations aimed at promoting peace. Key figures like British Prime Minister Neville Chamberlain pursued a policy of appeasement, most notably at the Munich Agreement of 1938, where they allowed Nazi Germany to annex parts of Czechoslovakia in hopes of preventing further aggression. However, these measures ultimately failed as Hitler continued his expansionist policies, leading to the outbreak of war in 1939.
