We had terrorists in this land long before Al Qaeda. We "Americans" were once the terrorists, as I recall. At least, that's what the British said. Then we began to call the Native Americans that. Then the Mexicans. Some folks drinking whiskey. But that's always a problem, I guess. John Brown. Hijackers from Cuba and Palestine. I doubt we'll see an end to it. No one who projects any power anywhere ever does. Ask our British forebears. Ask the French. Ask anyone. If they're still alive, that is. I guess you could even ask the Old Romans...if you believed in speaking to spirits. Always an obtuse idea on both sides ready to clash with the other.
But that's always a problem, too. And not solved by having a glass of whiskey, either.
