While reading the new George Carlin book I bought yesterday, I stumbled across this very fitting quote by Herman Goering:
Of course the people don't want war. But after all, it's the leaders of the country who determine the policy, and it's always a simple matter to drag the people along whether it's a democracy, a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism, and exposing the country to greater danger.
Incidentally, Mr. Goering said this while on trial for war crimes at Nuremburg. And it's true, as per snopes.com.
