Last year I heard a talk by retired Admiral Stravidis, who among other things was supreme commander of NATO for a few years. He pointed out that by the time somebody makes the rank of General or Admiral they will have sworn that oath a bunch of times. They renew that oath each time they are promoted etc. They also would have administered that oath to countless other soldiers & sailors over the years.

Fire all the generals and admirals, and guess what? They are replaced by junior officers who have repeated the oath to the US Constitution almost as many times. There’s always the chance that some may decide to bend the knee to Trump, but there are significantly more that likely won’t.
