That has not yet been shown. When it comes down to it, I wonder what the military will do. Will they uphold their oath, which is to the Constitution? Or will they obey the President, as commander in chief?
It is being shown daily. You're forgetting how things work in authoritarian states. In those countries, the military is AT ALL TIMES a risk for a dictator. They must be mollified somehow, lest the trucks with the armed men come rolling towards the palace.
In those countries, the military top brass will voice concerns privately, will leak unhappiness with the regime discreetly to other factions in the country. The US military is completely silent and subservient. This means Trump has their support. No one in the military complained when he bombed Iran or sent them to LA, for example. For all we know he did it for them. So Trump does not fear the trucks with men, and so has military support.
