It's never easy to admit when you're wrong, but I have to admit I was. I thought we could go in, stabilize the country, put the beginnings of a government and infrastructure, and get out. I didn't think we'd ever make it Connecticut, but maybe a Kazakhstan.
Afghanistan is populated with some of the worst people on earth. It will NEVER be anything even approaching some semblance of a civilized nation.
In retrospect, we should have told the taliban they had 72 hours to give up OBL, or we'd nuke Kabul. Assuming they didn't capitulate, give them 48 hours or we'll nuke Khandahar and Herat. Then 24 hours and we'll strike Jalalabad, Mazir-e-Sharif, and Kunduz. And so on and so on until we were relatively sure OBL was dead, or at least persona non-grata to any nation on earth.
I think it's been proved beyond reasonable doubt that muslims cannot be civilized and the only way to deal with them is to bring down the fires of hell when they step out of line.
