The biggest problem with a prophecy of doom is that countless individuals assign themselves the role as the catalyst of the prophecy. They make it their responsibility to make sure the prophecy comes true. What if our biggest threat from terrorists is not from people abroad, but from American citizens within our own borders? It has happened before. Will it happen again? December 21, 2012, will make prior terrorist attacks seem like a dress rehearsal when twelve men set on a mission to put fear in every American heart. It will turn Christmas 2012 into a Black Christmas.
