It's amazing to think of New Orleans as a glimpse into a post-Apocalytic future. People will continue to live there. If we had difficulty mustering the resources to get people out who wanted to leave, the effort to track down the humans who opt NOT to leave will be nigh impossible.
I imagine troops eventually pretending they are television crews or journalists to lure out those seeking 15 minutes of fame, all that's left to most of them, until no one knows what communities inhabit the swamp, since no one will trust anyone else. I could see this as an opportunity for Freemen to establish a stronghold in a place that has some industrial base intact, and even hold it against our significantly diminished armed forces.
And the fingers point clearly and unfailingly to our 21st Century anti-Christ, George W. Bush, for the magnitude of the messes we're in. I've dealt with people like him. In fact, I've dealt with some of his relatives, all of whom live in a world of power without accountability, where they relate only among their own, an American aristocracy. I want to envision a world where the human species survives, primarily because without that hope we are doomed, but it gets harder and harder as I see Americans, driven in large part by an Evangelical Christian right-wing agenda that has so successfully caplitalized on non-issues like abortion and homosexuality, supporting the moral depravity of a corrupt and violent regime.
