I think Americans are way too comfortable now to risk their necks, but if there was a civil war, it would be the absolute end of the USA.
China and/or Russia would watch you kill each other from afar, then just roll in and take it all, and nobody could stop them.
And where would all the millions of American refugees flee too, Mexico? Canada? Bridges are being burned there as we speak.
So, basically, your second post contradicted your first.Virginia policewoman shot dead on first shift
First, comfort is a matter of perception. Minorities are already revolting.
That aside, in the case of an economic collapse, nobody will be living comfortably. So, whatever dynamic you think is in play now will be gone. Including your false sense of security that your baseball bat will protect you.
America is no different than any other nation that is big and tries to subjugate a diverse people to a rule of singular mindset. They all eventually collapse and divide up.
Hopefully, it happens peacefully. Like the UK did after the 1800s. If not, it will be violently.
As far as being taken over by another country, possibly. Although our individual states are better armed than most countries. And you keep operating under the assumption that most of the armed forces will follow the federal government. Which, is doubtful.
Further, in the case of an economic collapse, China and Russia will have their own problems to deal with. China's financial capability is almost entirely dependent on us. Russia's is almost entirely dependent on China.
Without us, China won't have the means to have their energy needs met by Russia. So, there is as much chance that they will start fighting each other as us.
And, if they didn't? Given that we are pretty much the police force of the planet, there are far softer targets they could go after.
Sooner or later, a new government(s) would form here and things would stabilize.
