Tora bora... we cannot argue taht, fellahs. There was ONE north road out of tora bora.
The USA chose to leave it unbombed and allowed a 1000-car caravan to escape.

I can understand - you kill OBL then, and you can't get the wars you want. you NEED a boogeyman. if you kill hitler in 1940, we never get in WWII despite a pearl harbor.
So historically, in the name of winning wars, setting up bases, maintaining drugs and currency status quo... we HAD to leave OBL alive for a few more years.
if you disagree, grow up and take off the blinders and stop thinking with your moralisty or political siding. It is how the world works.
