WTF?
The Taliban will wait us out. 1 year, five years whatever. Either we have a permanent presence or they will just regroup and surround Kabul. In the lonng run, we’ll wear out politically long before they do. They live there.
Based on what little you said, two guys walking out the building shouldn’t be shot. The building has to be cleared or blown up before you know if they were, shooters, residents, all of the above or what. Even if they turn out to be the shooters they needs to be questioned to see what information might be obtained. Then, for my money, shoot em.
