god damn, why does everyone throw up the WWIII flag every time something happens? The US hasn't mounted a serious invasion or anything.
we've been hell of a lot closer.
we'd need at least a full scale invasion of syria and russia being more stubborn than ever before.
WW3 didn't start over ukraine, crimea, north korea, vietnam, korea again, iraq, afghanistan or anything else, all instances the US backed one side russia the other.
We've avoided WW3 every time. Even when china joins the party.
