America is not an empire. There is no comparison. The “powers” that fell were all empires, Persian, Soviet, Rome, Britain, Mongol, etc...explain the similarities...
To clarify, I did not call America an empire, I called it a “major world power”, albeit one with its fingers in practically every major issue going on in the world. True, technically we aren’t an empire, but our global influence throughout the world surpasses anything experienced by any “empire” that has occurred in history, IMO.
