And yet the second World War, the most destructive war in history, and fascism and nazism themselves, occurred within a generation of the end of the first World War, the most destructive war in their history.

Throughout history, war has always begotten more war. Look at the Middle East today: by your logic, it should be the most peaceful place on Earth by now, given how all of the people born there for the last 50 years had been through war (and often famine etc). And yet many of them are actively seeking more war to right the wrongs of the war before, or just because they see their neighbors are weak and it's a good chance to invade them and "rebuild our historic lands".
