What do you think could have been done or should have been done to avoid World War II?
England and France should have stopped Germany in 1936 when Germany took Czechoslovakia. Germany's army was completely unready at that point and was mostly in Czechoslovakia occupying it. They would have rolled over Germany at the point and could have deposed Hitler before he started WW 2.

Treating Germany fairly after WWI might have done the trick. Hitler's success in getting others to listen was in no small part because of the state the other countries had left them in.
