"Do you consider Saddam Hussein to be a terrorist?"
I've used that same question when debating some of my liberal friends. It really gives them fits. Of course Saddam was a terrorist: he terrorized his own people, harbored terrorits, trained them, funded them...he even was an eco-terrorist (oil well fires in Gulf War I).
Better yet: "Senator kerry, I know you missed over 80% of your intelligence briefings, but from the little information that you actually received, do you consider Saddam a terrorist, and if not, can you define what a terrorist is?"
