It would depend on the country, I would think. However, if the US goes to hell, what would the rest of western nations look like?
When the SHTF in the global economy, I would rather be here with our conservatives - American-Americans - than I would want to be with Europeans. I would rather be armed with Mexican immigrants who are much more like us than disarmed with Muslim immigrants who are nothing like Europeans.
Conservatives, if nothing else, will figure out how to create a decent community for themselves within a nation destroyed by Obama. Europe has no American-Americans to survive and thrive with.
