It's not quite there yet. Korea's conflict escalates, but there's still more mount to climb. Trump is increasing weapons sales to South Korea and Japan, based on a September 5 Tweet; North Korea called him a "strangler of peace" and a "war merchant". Mattis told the Army to "Stand ready". Hawaii is rehearsing for attacks.
Most of the talk is to get everyone psyched-up plenty of time in advance—soldiers, nations, and peoples. The timing, however, will come at a convergence of defenses being in place and opportunity being open. Then, the US will either strike with "just cause" or "strik-taliate" as it did with Pearl Harbor and the Lusitania.
In the meanwhile, expect the escalation to continue. Expect more Navy strike groups to be directed. Expect the USS Ford to replace the decommissioned USS Enterprise and the USS Reagan to replace the USS Vinson, somewhere in East Asia. Three aircraft carriers, two on their way in and one their way out is certainly a military peak. But, also keep an eye out for a shift in types of Korea-related headlines followed by a quiet from central command. Once the press release statements resemble a ship casting off, that's what you call a clue. And, we haven't been clued in quite yet.
