I'll admit all this sounds fine and dandy but, to be honest, all this stuff is based on a series of events taking place in the exact way these people predict them.

The US is definitely headed in a rocky direction but, I think these people are just a group of arrogant asses that want the satisfaction of telling the world "I told you so." They are no different than the religious groups that have been wrong time and time again about the end of the world.
