In one of the finest pieces of mind control and spin-doctoring I have ever seen, the governments leading the invasion of Iraq managed to turn a public overwhelmingly against the war into a passive consenters. How? By starting the war, and then saying "It's too late to object now."
Obviously, this is true, but if we let them get away with it, they might try it again.
Hey! Of course I support our troops! That's why I want them brought home now.
