First of all, I agree we should never have been over there to begin with. Yet.
If we ever committed the full force and weight of the American military, we wouldn't be having this conversation. however.
That was never going to happen and ((they)) know it.
But also, don't ever estimate a people's resolve to resist occupation, especially when the occupiers were never really NOT WANTED to begin with.
Afghan's are a old and proud people, they have resisted Empires for centuries, they're very good at this. It is a graveyard for empires overplaying their hand trying to conquer a tough people and coarse land with really not a lot to gain, it is usually the invaders hubris which compels them to continue on a exercise in futility. America is just the latest empire to realize this, fold tent and go home and cut their losses.
But kudos to the Taliban for resisting the NWO and send them packing.
