Hitler was a politician and as far as I know didn't go on his rampage but sent the people he had convinced that he knew best. Likewise Japan did not invade America but the Japanese obeyed their leaders who told them to invade for their glory. In a war there are two sides both have leaders and both have common people who have to die to prove their leaders right. Saying that though I have no answer on how to counter an agressor. It would seem in this world that might is right, sad though that is.
