No problem. I am personally not a huge fan of cross-societal historical comparisons when they aren't of the same time period, as political forces that seem similar are ultimately different based on their methods of production.

There are certainly lessons to be learned from understanding the end of the Roman Republic, but part of the reason that it went the way it did was to solve the political-economic contradictions that existed within Roman society particularly. Alot of the same historical forces are certainly at play in the U.S. but how they manifest themselves and play out will be particular to our own political-economic contradictions, which differ significantly from that of the Roman Republic, as we are (to a 4th or 5th degree) historical downstream inheritors to their solutions.
