Well, I think unless you go through many reforms, alotve civil wars and so much other stuff, your country/empire is always going to fall. Some of the stuff i lsited may even cause the fall ironicly. But the way America and Rome both began with the rights of the people, and as an republic. This type of gonverment is always best, but it can lead down to a road of bad things because our gonverment becomes so successful and powerful, that its our eventual downfall. I dont think Americas fall is anytime soon, but I think there will be a day that the United States will be a weak country, or an broken country. Like you said, so similar to Rome.
