Like most cases in history, World War II was the result of a chain of events. The Munich Agreement led to Hitler's invasion of Czechoslovakia, therefore in my opinion they were both huge causes for war. But like any other war, World War II was an accumulation of decisions and situations.

This agreement proved that France and Great Britain showed no interest in stopping Hitler, they basically handed each piece of land after the next on a silver platter for Hitler. Since all of the Czechs defenses were placed at the border between Germany and Czechoslovakia (which was now in German territory), Czechoslovakia was now defenseless and naked in front of Hitler. So you could say that because of the Munich Agreement, Hitler had the chance to invade Czechoslovakia.

Britian and France finally took action after realizing that their appeasement policies did not work and Hitler could not be trusted.
