The Chicoms are allied with the Taliban regime Al Qaeda ISIS as is Russia too.
You risk Russia funneling advanced nuclear weaponry to the Islamic Republic of Iran by pulling out of Afghanistan you risk China Russia pushing us out of Central Asia you risk 9/11 style attacks, on American soil by pulling out.

Sounds like one or more nations have got America between a rock and a hard place.
Perhaps our nation's focus should be getting us out of that position before it becomes too late.
Perhaps making a few announcements to our global neighbors about what is acceptable in terms of nations making hostile moves against or in other nations and then enforcing the issue would suffice.
Of course, with a Biden-Harris admin it is a moot point.
