i don't actually know jay's take on afghanistan but i'd like to hear it - he's obviously a very logical guy pat (speaking of "pat answers" ), but as you say, mcnamara was able to give voice to the problems of logic vs emotion near the end of his life - afghanistan certainly feels wrong to me - how does it feel to you jay?
I supported the invasion and our efforts to kill all members of Al Queda present there, displace the Taliban, and establish a civil framework that the population could at the very least have a chance to use to construct a government upon that was substantially less primitive, backwards, and barbarous than the Taliban.
I don't think that it will be possible to turn Afghanistan into anything remotely resembling a modern, prosperous, stable democracy so we'll probably have to settle for something far less than that, call it good, and disengage while retaining the capacity to attack and kill Al-Queda or whoever else shares their goals and tactics when the opportunity to do so arises. Something more ambitious might have been possible in other circumstances, and with less feckless and uncommitted allies and more partners like Canada and the UK, but that's clearly not in the cards at this point unless the Afghans themselves make it so.
So in other words our effort was doomed from the start.
