But the terrorists operate freely in many places around the world (we all know them)!
So, are we going to wait till terrorists cross into our borders even as they plan mass murders in various safe-havens? How are we going to deal with terrorism when terrorists can acquire weapons of mass destruction from rogue states?
That's why President Bush's policy of being on the offensive is great! It promises to deal with terrorism before it becomes a significant threat! It takes the war to them, where it belongs!
