A military order from a President will go through the Pentagon, the State department and multiple levels of undersecretary's and many chains of commands in the military.....If a President issues an illegal orders you would have multiple resignations throughout the whole chain of command....
But you guys need to believe in the myth of a dictators to compete this fantasy of an authoritarian Trump
....The bigger risk of authoritarianism by a President is using the administrative state,,,,such as packing the court, removing the electoral college... adding solid Democrat states,removing the filibuster........These are the moves of a fascist......and its the plans of the left...
