In the U.S. military, it is considered inappropriteto get nto politics, and that is why it is retired officders who come out against Trump. However, it is good to recall that when we go into the U.S. military, we take an oath to defend the Constitution against all enemies, both foreign and domestic. We do not take an oath to defend the government. Some years ago, when I was Ground Comm officer with a ANG fighter group, we got a TWX from NGB one day putting us on 24 hour alert "in support of the Constitution." I learned later that the regualrs got a similar TWX from JCS, but theirs was a bit more specific. It said that if they got any orders to arrest members of Congress or the Supreme court, that they wdre to ignore those orders. A few days later, Dick Nixon resigned. I don't know to this day if somebody at the Pentagon knew or suspected that "Tricky Dick" was planning something or whether they were just putting a shot across the bow as a warning, but our military takes that oath about the Constitution very seriously.
