EVEVTUALLY, the US will come to an end, of course. Probably not for a good while, though. Near-term, the most likely loss would be that of the Southwest to Mexico. THAT could happen in my lifetime!
The US is France/England in slow motion. SS going bankrupt and Muslims taking over sections of numerous states will certainly happen and raise tensions very high. But as long as Democrats can vote for free money, and no Voter ID cards are required, nothing can stop the cycle.
