This isn't a ceasefire. It's talk and fight. I imagine we'll be stomping the crap out of them on the battlefield in order to pressure them to give us a deal such that we can wave around a piece of paper and say "peace with honor", before handing Afghanistan to the Taliban. Vietnam could have been salvaged if we had continued funding the South. The Democrats cut off funding to make sure the Commies won.
If we continue funding Afghanistan to the tune of a few billion dollars a year, the government should prevail, although I expect the insurgency to go on for decades, much as the Philippines and Thailand have been fighting Muslim insurgents for the last 100 years. If we cut them off, the government will fall almost immediately, because unlike Vietnam, the place is frankly a wasteland of arid deserts and mountains, and there's not enough there to pay for the cost of fighting off a Taliban funded by Pakistan and private donors in the Gulf states.
I hear you. But I see no reason to send billions of dollars to this hellhole. We need to leave and then when it gets out of control dispatch drones. Don’t fix it. Just break it periodically when it severely threaten our interests. We cant get rid of radicals but we can make it difficult for them to grow and hurt us.
