Terrorism involves the moderate Arab states, too, and the last thing we want is for Islamic fundamentalism to spread to these states. Who killed Anwar Sadat? Who sprays tourist buses with gunfire at the Pyramids?
If we manage this war wrong, it will backfire and we will have less friends in the Middle East. We simply can't afford that.
The actions we take MUST take these considerations into account. I don't believe that Ronald Reagan would have handled it any differently. He was no fool, either.
NO QUARTER!
