Several separatist movements in Europe already play a major role in the national politics of their respective countries. I believe there is some potential for similar movements in America. Is it possible for them to get political recognition and approach their agenda peacefully?
What will happen to the United States in this case and how the federal government is going to respond?
the Fed would kill everyone that tried.
just look at history
We are living in the XXI century after all. It is not that easy to kill your own citizens, especially when supported from without. International community won't let our government do whatever it wants. It is much easier to destroy the movement from within than start a full-scale military operation against separatists.
you think other countries would came and stop the Fed?
you do know that it's us that carries the heavy load around the military world?
really, no one would come help, Canada might let refugees in, but that's it
