The fighting terrorism argument makes no sense. Invading a country will always build a determined opposition, who could strike here as well as there. Plus, given the current dismal state of the economy, we can’t afford to fight wars that don’t need to be fought.
It’s my suggestion that, in the big picture, our hand is being forced. Our economy and long-term prosperity is threatened by the fantasy that the US can forever maintain an increasingly expensive war enterprise. We need to ramp down this business of Empire before Lady Liberty gets the wind knocked out of her permanently.
