Which do you think was the biggest cause of the war- the Munich Agreement or Hitler's invasion of Czechoslovakia?

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.

It was a conference held between the major powers of Europe to discuss Hitler's demand …

…both incidents caused and contribued to the outbreak of war. The Munich Agreement allowed Hitler to invade Czechoslovakia and Hitler's invasion of Czechoslovakia showed the world what his true aims were. Hitler didn't just want to unite Germans together; he wanted world domination in the name of Germany. Countries began to realize the only way to sop Hitler was the unavoidable decision to fight and that led to the eventual outbreak of World War II.
