The US typically doesn’t respond well to threats though, because the perception of military might is so important to their foreign relations. With The Taliban making “or else” threats it becomes a seesaw between whether it’s worse PR to crawl off with tail between legs and make it look like The Taliban has the power to issue threats to the US unanswered, or to make a U-turn.

If they simply choose to ignore the threat and the Taliban does implement “consequences”, there would certainly be retaliation.
