Yeah. The US is too powerful to escape while it’s unified. The modern “Berlin Wall” is made out of federal agents and extradition treaties in almost every country that isn’t a tyranny itself like China, Russia, Iran, etc. The answer lies in significant scale secession within the US. Doesn’t have to be formal. It really just needs to be the refusal to enforce federal laws and taxes and stick to it when the violence arrives from the feds.
