It does not matter if the country supports or fights or grants neutrality to Taliban. The Taliban have no regard for borders except to find a country that will accomodate them.
Therefore we should disregard borders, nasty letters from their governments, useless visits by Ambassadors, threat to trade agreements and tourism.
Just go in there and destroy Taliban hideouts, training camps, etc. Unfortunately, there will be some "innocents" killed also. I put "innocents" in quotes because if they are mixed in with Taliban, then they are probably supporting the Taliban. If it's a case that they are true hostages, perhaps a more personal and close up engagement is necessary, like Special Forces.
But either way, the Taliban has to be wiped out either by live fire OR (preferably) re-education that their style of power is hated by everybody else in the world and it is they that must change. Joining the rest of the world in common goals is better than holding children hostage, threatening lives of innocents and eventually getting a .50 caliber bullet from a Barret through the lungs.
