While I don't agree with his theory, I do think that America is headed towards a civil war that will be far worse than our first one. Our country is actively consumed by two inconsistent ideologies constantly fed to us by our new media and our two political parties/collectives of parasites.
What is likely to happen is a civil war between the most rural states (dominated by "conservatives") and the most urban states (dominated by "liberals"). Who would win? That's up in the air. The Government and Military would be split in half so each side would get an equal portion of the troops, so it'd come down to whether or not the "left" would be hypocritical enough to take up firearms against the "right". Also, it depends on how unified each side is, and since the "left" generally professes itself to have more diversity than the "right" it would be more susceptible to internal division.
There is also the possibility of military intervention from other world powers such as China, Russia, and the European Union, all of which would likely assist the "left" as that faction would be more willing to accept foreign demands.
I do not agree with the time this guy has set up. While I do not believe in the 2012 Theories, that year would be the most likely for a civil war to begin as it would likely be a race between President Obama and Sarah Palin. Either individual achieving victory would be the catalyst for a complete split in this Republic.
