Can we Americans just decide to finish and win, for once?
The drama to Afghanistan tends to be the fact that we've already "won" with regard to many of our initial goals, but yet the definition of a "win", and what it means to us as a populace, depends on where you sit. One side doesn't believe we've finished the job, because the Taliban oppose us and the guy we propped up to be Number 1. If they come to power, then Al Qaeda is going to rush back in. The other side believes that Al Qaeda will never have the same foothold it did before November 2001, in Afghanistan, and that we need to stop wringing our hands over the possibility that the Taliban may come to the fore and run a crippled state.

Erecting a wobbly government that cannot support itself without significant aid injections, and at the cost of a significant amount of our national treasure in lives and money, may make it a Pyhrric victory that we cannot afford.

Again, it all depends on where you sit. "Wins" are not black and white anymore.
