Actually, even "before" things weren't like "the way it was before". That is, nothing has really changed at all, only perceptions have. There has *always* been terrorism, and terrorist acts against Americans. We can't turn the clock back to a time when there weren't, because there never was such a time.
I'm reminded of Yogi Berra's comment: "Things are more like they are now than they have ever been before".
Either that, or kill every damn one of them.
Or maybe we'll get lucky, and whatever God might exist up there will make an appearance to say "Knock it off, dammit!" Unless God is some kind of sadistic nut, I would expect that to happen if things really escalate. Religious freaks, please don't use that thought as an excuse to hijack this thread, please.
