Greg,
The statement by Biden is significant - when considered along with the following:
"[W]e can now remove almost all of our forces from Saudi Arabia. Their presence there over the last 12 years has been a source of enormous difficulty for a friendly government. It's been a huge recruiting device for al Qaeda. In fact if you look at bin Laden, one of his principle grievances was the presence of so-called crusader forces on the holy land, Mecca and Medina. I think just lifting that burden from the Saudis is itself going to open the door to other positive things."
Who said this prescient bit of wisdom ?
Paul Wolfowitz, back in 2003.
Now, if just the mere presence of troops, who were not actually at war, is such a source of "great difficulty", how much more would the potential difficulty be, if are troops are in places where, due to the nature of the war, the combatants are largely indistinguishable from the civilian population, and as a consequence, significant numbers of civilians are dying - particularly when one consider that one of the fundamental tenets of Islam is that
"an attack on one, is an attack on all" ?
