European leaders believed that appeasing Germany would prevent Hitler from taking further aggressive actions and would eventually lead to a peaceful resolution of the territorial disputes in Europe.
2) The fear of Germany’s military strength and the belief that Britain and France were unprepared for war:
Germany's military spending, remilitarization of the Rhineland, and territorial expansion had significantly increased its military power. Many leaders believed that Britain and France were not adequately prepared for a military confrontation with Germany and that appeasement was necessary to buy time for strengthening their defenses.
3) The influence of isolationist sentiment and pacifism:
After the devastating experiences of World War I, there was a strong desire among the general public in Britain, France, and other European countries to avoid another major conflict. This pacifist sentiment influenced the political decisions of European leaders, making them more inclined to pursue peaceful resolutions rather than confrontational actions.
