Yes, probably. Obviously, none of the states has the resources to challenge the US militarily
Well, that is assuming the US military could be used to suppress an insurrection. Maybe the National Guards could, but who would they side with...Obama or their home state?
Personally I'd like to see certain states kick their filthy RAT cities out of their state boundaries. Then the cities could link up.
How about..."The United Cities of America"?
In 2008, Bush signed into law 10 USC Section 333 which seems to apply.
A lot folks would agree with your idea of isolating cities. ;^)
For a long time I’ve thought THEY could have all the ‘blue’ cities and counties and WE take all the red counties (not sure there are any red cities). See how far that takes them.
