Trumpy is not into governing ... he is into RULING.

He will never understand that his job is to serve the public (as a public servant), not RULE the public.

THIS is why this episode won't end well and he will likely go down in history as the worst President ever.

Pro tip: Americans don't like to be RULED.

A soldier is obligated to refuse orders that are "manifestly unlawful""that is, orders that any person of ordinary sense would know are wrong or violate the Constitution, international law, or the Geneva Conventions. Following an illegal order can lead to prosecution for the service member.
