Scary speculation on last night's news. With the firing of H.R. McMaster (Nat. Security Advisor) and the soon-to-come firing of Jim Mattis (Sec't of Defense) -- both replaced by John Boulton the Fox News chickenhawk who served domestically in the National Guard yet wants to
pre-emptively invade North Korea and Iran -- Trump is systematically removing everybody with any military experience who counsels him against using the military injudiciously.
At the same time Trump's options for derailing the Mueller investigation are narrowing. Even his supporters in Congress (his jockstraps?) warn him that firing Mueller would lead to a constitutional crisis and an impeachment action.
So.
I think
he's positioning for a war to distract from his personal legal troubles. As soon as Mueller hands down indictments (or is about to) Trump will fire him, close the investigation, and invade either Iran or North Korea or both.
