Folks.....remember what happened about 2 days before the Tiananmen Square massacre. The ChiCom ordered a Chinese army division into the square but its general refused. He said he was not going to attack unarmed citzens. The ChiComs used another army with a more agreeable general.
It is very likely that our Army Generals will refuse also.
Keep in mind that Hussien’s army may have to go through a state’s national guard first. A governor could thwart Hussien’s bid for conflict by using the state’s national guard.
Or most of them will, anyway... I hope.
