Which brings us to a flaw in the Trump administration’s thinking on Afghanistan. ... Taliban is supposed to ensure that terrorists don’t lash out at Americans from Afghan soil.... this doesn’t make any sense. The agreement rests on a whitewashed view of the Taliban and its decades-long and unbroken alliance with al-Qaeda. ...It’s a good thing the Germans, who may have received some assistance from their American counterparts, intercepted the ISIS cell. The Taliban didn’t—and there’s no good reason to think it will disrupt terrorist operations in the future either.

I understand war-fatigue. But a small contingent can do a lot of good. I'm not sure we are making the right choices, and I'm sure we aren't making them for the right reasons.
