The most we can do is support the locals help themselves. Countries that are going to do something include Russia on the Northern border, China to the east, India and Pakistan to the South - and probably Iran if they got ideas above their station and possibly Russia to the West. The others might well do so if they aren't keen on pretending it's 550AD with oppression of almost erything.

Expecting that anything can be accomplished without significant local support is dreaming. When the population decide they like what they've got better than what the Taliban offer then you've got a definable border to defend. North Pakistan doesn't fit this criteria, so no wonder there is so much difficulty removing the Taliban.
