Honestly, he probably won’t. Speaking in very broad strokes, you can put narcissists onto a continuum between “aggressive type” and “avoidant type”, which more or less defines how they respond to emotional overload.
Trump falls more into the avoidant type, only fighting battles he thinks he can win “aggressively”, but immediately turning tail and running away from losing ones, trying desperately to change the subject and move onto something he can “win”.
He’ll bluster and sort of try to feel people out to see if he can get them to fight the scary stuff for him, but nobody’s gonna back him on martial law, and he’ll retreat when he’s rebuffed. Sometimes it’s a blessing in disguise that he’s such a dickless coward.
