IMO, you simply aren't paying attention if you don't at least question this situation.
OBL's rise to where he was, was facilitated in large part by our own CIA. That is not a black and white, apples and oranges world. With the suppossed end of the cold war, the massive military/intelligence complex in the United States needed a new bogeyman, none was more perfect than OBL, and then ultimately the "organization" coined Al Queda. The perfect rabbit hole for resources and trillions upon trillions of dollars, an enemy not in plain sight, that didn't ride over the hill in tanks and troop carriers, an "enemy" that could be defined and redefined again and again by the government.
