I read a book a long time ago about the Hungarian Revolution and when the USSR put it down, they did that very kind of thing.
They knew that the soldiers would be reluctant to fire on relatives, friends, etc, or even anyone of close ethnicity.
So they imported Chinese soldiers, who hated white folks, and those soldiers dealt with the rebellion very ruthlessly.
Likewise, they sent Eastern European soldiers over the the Far Est to deal with troubles in Asian countries.
They used racial hatred to accomplish what they couldn't get done otherwise.
So I would not be the least bit surprised to find a dem controlled federal government bringing in troops from an America unfriendly nation.
I agree with you. I don’t doubt for one second that the commies here would call in the Soviets or Red Chinese or even the North Koreans to shoot at our people. They will invade with planes, troops, tanks, artillery to shell the cities, use nerve and bio weapons. They will use an event like that to actually overthrow the commies here and take control of this nation.
