Nothing about Afghanistan makes any sense. Except at the very beginning there was no goal and, after 20 years, there was REALLY no goal.
But we did have a valid reason, at least AT FIRST...and then suddenly we heard "I don't really know where Osama bin Laden is, don't much care".
As long as we were focused on getting OBL I was firmly in support of Af-Pak.
I think that IS the point at which our mission just began to turn into a fuster-cluck. Suddenly we're guarding poppy fields with US troops, because if we crush the opium trade we're harming farmers, but if we guard them, then we witness the scourge of what that product represents.
I can't think of any set of choices that sound good.
