Dexter Filkins assesses the chance for “victory” in Afghanistan:

The Iraq analogy is useful again. There the military hung in, and got it right, and also got lucky. In some ways, really, they got a miracle. But strategies and policies generally do not deliver miracles. Can we expect a miracle in Afghanistan? Of course not. But it may take a miracle for us, and Afghanistan, to win.

So, it will take a miracle to win, where “win” is defined as “Iraq”.  Awesome.
