We should have never been there in the first place. But I hate the back seat condemnation of US forces like this is somehow unique to us. NO ONE HAS EVER SUCCEEDED IN AFGHANISTAN. Not us. Not the Russians. Not the British.
No one except the Persians, Greeks, Kushans, Arabs, Mongols, Tamerlane and the Mughals, you mean, to crib someone else's notes

Don't really disagree with much of what else you said, but there's been plenty over the course of history that held on to the region in question without getting eaten in the process. There's also very few that have had their control of the place collapse quite so
spectacularly as we have this round, from what I understand.
We definitely shouldn't have been there, though, and we extra definitely shouldn't have been propping up the
kid raping sacks of shit we did while we were there, just as one "well, maybe that was a
mistake" among a pile of them.
There were some serious,
serious problems with the groups we were supporting in that country, and it's turned around to bite... well, not us, really, but all the folks we fucked over when we invaded to begin with, and all the folks about to get ruined now that the shit we were holding up is collapsing like the rotten house of cards we helped make it
