You ever studied geography? Florida, the entire east coastline up up to Virginia? The gulf states? You forget they have seas too?
I say isolate them and let them survive on their own and have to deal with us as another country. It won’t be long before we start getting some super-ports in the gulf and other places.
BTW, secession was the Union’s interpretation of a rebellion. It was not the interpretation of dealing with a region that freely joined a union without expectation that they could NEVER decide to leave. That concept of permanent entanglement is just as bad as slavery.
So your solution to the international socialist effort of flooding our country with illegal migrant invaders is too let them stay and then carve up our country? Your mangina is showing.
Your philosophy of neutered conservatism is what let the far-left infest every institution in this country.
