On the one hand, appeasement can be seen as a major contributing factor to the outbreak of World War 2. By failing to take a strong stand against Hitler's aggressive actions, such as the remilitarization of the Rhineland and the annexation of Austria and Czechoslovakia, the Western powers allowed him to gain strength and confidence. This ultimately emboldened Hitler to launch a full-scale invasion of Poland in September 1939, which sparked the beginning of World War 2.
On the other hand, it is also important to recognize the role of Hitler's own actions in causing the war. Hitler was a ruthless dictator who was determined to expand Germany's territory and establish a new world order. His aggressive foreign policy, expansionist ambitions, and disregard for international law and treaties were the root causes of the conflict. He was willing to use military force to achieve his goals, regardless of the consequences.
Ultimately, both appeasement and Hitler's actions were integral factors in the lead-up to World War 2. Appeasement may have provided Hitler with opportunities to strengthen his position, but it was his aggressive actions and disregard for the rights of other nations that ultimately led to the war.
