You people are so selfish. All you want is to end a pointless war after merely 20 years, and tens of thousands of innocent civilians being murdered.
But have you given even a thought about the wants and needs of the CIA, you selfish bastards?
No! Our murderous spies are people too, and they don't want to leave and you can't make them.

CIA Director William Burns told the Senate Intelligence Committee in April that the CIA wouldn't be leaving Afghanistan when the military did.
"The CIA will retain a suite of capabilities, some of them remaining in place," Burns said.

So there! They won't be leaving because they need to continue all of their good work in Afghanistan.

CIA critics say operations in Afghanistan, Iraq and elsewhere were plagued by serious problems. They say abusive interrogations of suspects amounted to torture, and drone strikes sometimes resulted in civilian deaths.

OK. Sure there were all of those Afghan wedding parties that they blew up, not to mention at least five drone strikes that killed 39 children or more EACH. And there were those war crimes. But you can't make an omelet without breaking some knee-caps, amirite?
And it's not like Afghanis minded about being tortured to death or blown up when Americans were doing it. Because we're the good guys.

Fortunately, the CIA has a back-up plan.

In effect, Washington is seeking to reposition some forces in Uzbekistan and Tajikistan, which means that the first-tier troops, drones, bomber planes, and intelligence assets to be placed at bases or appropriate facilities in these Central Asian countries remain available in real time for intervention in the war against the Taliban.
As in Syria, local Afghan militia groups can be brought into the fight against the Taliban. Afghan warlords have worked with the Pentagon and the CIA previously.

Oh, good. Afghan warlords. Everything always works out when you partner up with warlords.
