What about another scenario, maybe a bit too realistic. If he thought he was going to lose the election in November 2020 or if he won re-election but say two or three years in to his final term - would you put it past him to start a war either by provoking any state (so-called enemy state or other) in to taking action or simply by taking action himself by attacking another country?

Any such scenario could invoke a Franklin D. Roosevelt style of remaining in office for the duration of the war and beyond so would Trump be tempted to go down that line?
