Gen. Mark Milley: We are unique among the world's militaries. We don't take an oath to a king or a queen, or to a tyrant, or a dictator, and we don't take an oath to a wannabe dictator. We don't take an oath to an individual. We take an oath to the Constitution. It is that document that all of us in uniform swear to protect and defend against all enemies, foreign and domestic. We will never turn our back on the Constitution. That is our North Star.
