Anyone seriously considering this is sorely mistaken.

When dictators consolidate their power, they purge their administration of anyone who does not pledge their supreme loyalty to them. The principled ones of course quit immediately, but without a doubt there will be significant number of people that remain. They are only human, and they have to deal with exactly the same problem that anyone else quitting their job faces in America today. Their minds will rationalize the actions, the Dictator will provide ample bogeymen as targets of hatred.

And even if they DO disobey an order, an American where the military no longer obeys the Civilian Administration... however terrible that might be, would be a dangerous line to cross. All bets are off at that point: the American military is the largest, best equipped fighting force the world has ever seen. Whoever commands it instantly commands immeasurable amount of power.

Of course, I hope that line is never crossed

When has any military ever stopped obeying criminal orders? I’m sure it has happened before, but I’m sure they are rare and isolated cases.

In the Kent State shooting, 58% of people blamed the students.

I would not bet on that happening before way way too late. Think if Guantanamo.

And anyway there's still a lot of space between this and the army shooting on the crowd (which happened in many places in the world historically).

Including the United States at Kent State.

They obeyed orders and participated in the illegal war in Iraq.

lol at the idea that the military will disobey orders... if they're going to disobey orders it'll be to start a coup...
