The Taliban is currently the ruling authority in Afghanistan and the money that would be released already belongs to Afghanistan. If they misuse their own money, that's their fault, not ours. America can't be blamed if it releases the billions of dollars now being frozen in EU banks to its owner. If the owner of that money misuses it, that's on them, America can't be blamed for all of those starving children. The sanctions also need to be lifted because that only hurts the common people.
As far as the Taliban being a brutally oppressive regime, that might be true, but you're not helping the situation or improving the lives of the average Afghan by starving them. Saudi Arabia is also a brutal regime and yet we maintain relations with them. Stop trying to save the world and being a self-righteous do-gooder. When you do that, you cause more harm. Let the Afghans eat.
