What were the effects of isolation and appeasement in Europe?

Isolation and appeasement in Europe during the interwar period allowed aggressive totalitarian regimes, particularly Nazi Germany, to expand unchecked. The policy of appeasement, notably exemplified by the Munich Agreement of 1938, emboldened Hitler and undermined collective security efforts, leading to the outbreak of World War II. This approach also deepened divisions among European nations, as countries struggled to balance their national interests with the desire to avoid conflict. Ultimately, the failure to confront these threats early on resulted in catastrophic consequences for Europe and the world.
