There is zero chance in hell our nations go to war over fucking Syria. Neither of us give a fuck when you really get down to it (or we would have massively intervened years ago).
Only reason Russia gives a shit about Syria is Assad let them have a port there.
The US/NATO and Russia isn't going to war anytime in the near future. Russia would get curb stomped in a conventional war and likely resort to nukes - and in that scenario everyone loses.
And no one be OBKFS and start going on about a Russia/China alliance against the west and everyone else.
Because that shit would never happen, and the US would still win
