I stole this quote but it fits the genre of what you are saying;

Hermann Goering put his finger on it in 1946, not long before he committed suicide. Gustav Gilbert, an intelligence officer, interviewed him in his jail cell at Nuremberg during the war crimes trials. The transcripts of these interviews were published in 1947 in Gilbert's Nuremberg Diary. Gilbert said to Goering that in a democracy the people have some say through their elected representatives and that in the US only Congress can declare war. Goering's recorded reply was: "That is all well and good, but 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 danger. It works the same way in any country."
