you know Rome had a senate on Capitol hill also, and eagles on their coins and bread and circuses.
Whoa! Did you know that they also had large roman columns on the front of their senate, also originally had a Latin motto, and were known for their domes (JUST LIKE THE CAPITOL BUILDING!!!!!!11!!). ITS A CONSPIRACY!!!! Reptillians! CALL DAVID ICKE!!!!!!!!!!!1111
...or maybe many aspects of American government and architecture are modeled after Roman concepts.
Your whole thing about empires is ridiculous. Of course they rise and fall in similar ways- they are all filled with humans and controlled by humans.
