Is that Before or After you began to figure out who/what and where al qeada... bin_laden (and the Taliban) and Saddams catalyst role in the whole big picture-- are and were...or after.<quoted text>
I will answer your question.
Upon learning who was responsible, I would locate & launch strikes against them
I would not invade a country (Afghanistan) & be stuck nation building. Afghanistan had little military strength. We should have ignored it unless attacked.
I certainly would never call Bin Laden irrelevant, abandon Afghanistan to go into an oil war.
As in--ultimetely you just basically stated-upon all intel IN and considered--you would've done the SAME exact thing that WAS done-You DUHmmy Moron.
