Anybody who entertains the hope that terrorists can be placated or that they will see our surrender or inaction as some kind of final victory for them is so seriously deluded it's laughable. Who were we bombing all through 2000-2001 through Sept 10th? Who was the USS Cole shooting at, who was threatened by the American embassy in Tanzania?
You don't bargain with these people. Our inconclusive end in 1991 is what lead us to this point now with Iraq.
