Oh my good. Russia now controlles a bunch of usless desert with no stratgic value in a country that is totally destroyed from a civil war.
The impact of importance of that even has literally zero impact the actual people of the US.
Going their was to defeat ISIS, and that is mostly done. What's left can be handled by local forces.
The only dumb thing here is that the US even built these bases. Utterly idiotic, but the military always has the money and sturts building bases way to big. The same thing happened in Iraq, where the bases were taken over by ISIS.
How about you just stop building bases in places where it doesn't make sense to station troups long term. Of course the military then uses these bases as an excuse for not leaving "we can't leave, or they will get these bases". Its incredibly dumb.
