Remember the Chinese military had no problem mowing down protestors if their bosses give the order.
That said, it is easier and safer to defend yourself from a government in modern society with information and free uncensored communication than with guns.
You seem to be completely off-base.
No, in the United States, the military and all federal employees explicitly swear an oath to the Constitution, and are forbidden from executing illegal orders, regardless of the chain of command.
Yeah, PLA goons in Communist China certainly do things differently.
In the United States, the people are the government. Where are you?
Also note all the leaked footage of our military gleefully mowing down children and keeping score. They are never prosecuted for war crimes either. Just part of the job.
That is how humans work everywhere. The US is not special.
Yeah, you've never been in the military and appear to have a knowledge based on memes of it. Read the officer's oath and see what we're trained to do.
The other three cases were all wars - an apples to oranges comparison.
