What was the most stupid thing the League of Nations had done? We can choose the failure of the League in Manchurian crisis and Abyssinia crisis, because these became important cause of World War II.

Therefore, I think Abyssinia is more terrible affair to the League. But it's true that both Abyssinia and Manchurian were very important affair to the League (bad effect)
