I mean lets be honest, Rome didn’t really collapse, it moved to Constantinople and continued on for like another 800 years or something I dunno. Then over time became smaller and smaller for about 10 different reasons all disputed, until the Turks took it and the ottoman empire was established. There are a lot of things that cause an empire to collapse, maybe its way of doing things just cannot compete with other types of countries or entities that seek to remove it from power, or maybe its forced out, or a coup is thrown and things change all together. I don’t think the United States has fallen to this yet. I think the fall of the U.S. will either be internally via some kind of civil unrest/war or an uber fail economy, that weakens the dollar and the world is no longer reliant on the dollar to do things like industrialize, or what ever. (this is kind of close to happening but hasn’t happened yet). As long as the world needs Dollars the U.S. has a bit of a monopoly on the world. And who ever said the United States isn’t an empire, we only conquered most of north america, annexed a few islands, exploited south american countries as if they were colonies, and have military bases all around the world. We also own the moon I think… (since we landed on it first?) (dont start conspiracy bs)
So, to answer your question No, because 1 we haven’t split the country in 2 with two capitals, there hasn’t been a major change in morals or religion (pagan to Christianity) We are still a democracy (Caesar over threw the Senate) We are still the #1 economy and other countries rely on us as far as that goes, The military is the most effective and far reaching in the world and we don’t have the same problem of assimilating other nationalities or races that come here or are absorbed.
The U.S. is really just coming down from being the hegemon in the world, but we are not collapsing. (use hegemon in your paper your teacher will jizz his pants)
