From the post:
While many who say this are merely fashion-parroting sheep rather than committed anti-Americans, if someone you believe to be a genuine anti-American says they oppose the Iraq War because "there were no WMDs" or "Bush lied about WMDs", then you can merely ask :
"So if WMDs were found, would you support the war?"
They can either answer "no", to which you can say "So why do you obsess over WMDs if you still would have opposed it anyway? That appears rather phony on your part."
Or they can answer "yes", to which you can ask them "But Iran and North Korea are openly admitting to the pursuit of nuclear weapons, and are threatening to use them. By your logic, invading them is fully justified, is it not?"
They have thus revealed that they merely avoid taking difficult decisions, in order to criticize from hindsight and mask their anti-Americanism in pseudowisdom. Either way, they are trapped. This is so simple, yet very effective. In reality, they oppose any action by the US because they oppose the very ideals of the US. Yet, they are too ashamed to admit it, and so hide behind phony guises.
