My brother-in-law sent me this quote by Herman Goering:

People can always be brought to the bidding of the leaders. Tell them they are being attacked and denounce the pacifists for lack of patriotism.

A longer excerpt can be found here.

BTW: some pages attribute this quote to the Nuremberg trials, so I tried to find the quote in trial transcripts:

• Douglas Linder has an amazing page of transcript excerpts from famous trials, including Salem Witchcraft, O. J. Simpson, Rosenberg, Nuremberg, Hinckley, Galileo, Socrates, My Lai, Chicago Seven, etc. Remarkable.
• The Nizkor Project has the complete Nuremberg transcripts online.

Turns out, the quote isn't from the Nuremberg trials, but it's close: it seems to be from The Nuremberg Diary, by a psychologist working with the Nuremberg defendants in prison.
