Who’s selling them their guns? How are the weapons getting from source to user? Interdict and destroy the highways, trucks, gasoline supplies. “Disappear” the agents who broker the transactions. Intercept the weapons, sabotage them, then deliver the defective supplies to the enemy. Poison their food stores and water. Make every breath they draw a question mark.
Interrupt their money conduit. Track down their couriers and cut their throats. Then use the money yourself. Find the money sources. Convince them that their bucks can be spent more wisely ... like on insurance. Find out who’s getting paid and why. Make them hurt.
Compromise their intelligence community. Infiltrate. Disinform. Set them up. Ambush them with their own need to believe. Eventually all trust breaks down and the organization becomes paralyzed.
Destroy their command and control. They are fanatics and madmen with plenty of zeal but no direction. Take away the directors and you shatter their illusion of superiority. If we can get to bin Laden, the average raving diaperhead doesn’t stand a chance. Make them know that, dangerous as it is to resist the Taliban, it’s vastly more dangerous to piss off Uncle Sam.
Bingo.
Make war on their money. Find the donors, kill them and their families (no arrests, no trials). Find out who handles their money and ditto. State actors should be subject to massively destructive “black ops.” Spray poppy fields with most carcinogenic defoliants we can find.
Shut down NGOs providing food and medical care. Drive off the livestock, poison and demolish their wells.
Kill any “news” reporters or cameramen that try to help them with propaganda features.
IN the end, they need to be reduced to starving and freezing in the caves. Then, we’ve won.
