I only agree with part of what you said. But then again what you said about the NSA fiasco is true. I don't understand how people don't care that their 4th amendment rights are being infringed without the knowledge of the public! At least with the gun control, people are aware that it might happen. Then again, I never believed that a private citizen should have an assault weapon. Who the hell needs an assault rifle?!? And don't tell me it's for self defense!
But what you said about likening the current situation to the fall of the roman empire is false IMHO. Such a superpower can't just live for only a few centuries except for a few circumstances ie a world apocalypse.
Your points are taken, and all very valid. However, with the acceleration of technology and overpopulation, things are happening faster. I do agree that if the US fall, it will be massive caos, or perhaps because of massive caos the US will fall. We can call it an apocalypse. I don't like that term though because it is so inherently related to the dumbest, most evil fairy tale ever told: The Bible.
