“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.”
“There is one difference,” I pointed out. “In a democracy the people have some say in the matter through their elected representatives, and in the United States only Congress can declare wars.”
— Herman Goering at the Nuremberg trials
