No, it's just that most Americans have recognized that the "cave dwellers" finally figured out how to hijack and fly our own planes into our own buildings. Then they figured out how to make (possibly in their caves) and deliver anthrax through our own postal system. Then they figured out that they could send snipers to our Capitol and suicide bombers into our warships, hospitals, and embassies.
Once these Americans realized that the world's "cave dwellers" weren't going to be content to remain passively inside their caves, they apparently decided to start doing *something* about it.
Which is lucky for the cave dwellers. Had it been me in charge, I would have nuked entire continents. Then I would have unleashed chemical and biological weapons upon the survivors. I would have wanted to reset the entire planet and start all over with just our own continent. After all, I was pretty pissed off on 9/11/2001. Lucky for our enemies and those unfortunate enough to be near them, cooler heads than mine prevailed here in the U.S.
Instead, we'll compassionately use very limited force in very limited areas such as Iraq, Iran, North Korea, Afghanistan, Liberia, and possibly Cuba to ensure that your "cave dwellers" figure out that the U.S. is serious and that their own survival interests favor peace.
Of course, we may just be one or two successful large-scale terrorist attacks against us away - for people like me to come into power, and a far less compassionate solution being applied globally.
And that's what appeasers and terrorists should fear; someone far less compassionate than Bush or Cheney being in charge while the U.S. is being attacked.
GWB is a much better man than people like me, after all, and they would be wise to be thankful for that fact.
