so, what you're saying is that in the modern world, it is IMPOSSIBLE for any new country to be born?
this seems like something the British might have said in 1770…
Russia has NEVER invaded another country - they have insufficient population to ever control the USA - logically, your words are more 'muh Russia' bullshit and free from logic.
China could send their armies, provided the rest of the USA was complicit in letting them enter the USA - total loss of sovereignty for the rest of the USA? Again, logic fails.
Not saying that the recommendation is incorrect - but the reality is that there is only ONE state that COULD secede - Texas. This is due to energy, food, ports and size f economy. Yes - they could "nuke us from orbit" - but they can do that to anyone now. Talk about some optics to set the world ablaze….
If you are not willing to exercise freedom principles in the USA as a country, it will Balkanize - because that is the reason this country was birthed in the first place…
