The People’s Liberation Army is the army of the people. It’s in their name- PEOPLE! There’s no chance they will fire on crowds of protestors in Tiananmen Square.

China's got a different form of government. It's a different military culture. There's no division of power between the central government and states, there's no constitutional protections against the federal government using force against the people, there is zero chance that any of those folks in the army of the people would face any negative consequences for what they did, and no plausible basis for them to refuse to do it. If the central government wants them to fire on the people, it isn't illegal and there's no institutional resistance to it.

The U.S. isn't like that. Trump doesn't control the state government of, say, Pennsylvania. The governor doesn't derive political power from Trump, and doesn't have to answer to Trump. That governor doesn't have to roll over to Trump's commands. That governor also has a military force - tens of thousands in the National Guard and state law enforcement.

Again, this is just absurd. Trump is too weak and cowardly to try anything like this, none of the military people involved are actually long time deep allies of his, and they're not going to risk spending the rest of their lives in jail and being the villains of the darkest violation of American Democracy just because Pete F'ing Hegseth tells them to do it.
