Reputational damage? Are you forgetting that the Taliban were utter bastards who banned female education, were unrecognized by most countries and murdered 3,000 US civilians one fine fall day? The reputational damage is done because we didn't kill them all when we had the chance.
This deal is capitulation. Only this time there won't be refugees grasping at the skies of helicopters. We'll just lock them out and watch the Taliban kill every educated woman in the country.
