I'm a young whippersnapper, but how is the current state of affairs more "WW3" than what happened in Vietnam and Korea? To me it seems we're back to cold war.
Russia is a hell of a lot closer to world domination than it was in 1950 or 1970. If anything, the prior "peak" was in 1945, when Stalin failed to call Truman's bluff [1]. Parenthetically, the Haberdasher is the unsung hero of the eight-ish decades of Pax Americana.
