No, it has already happened. However, I am beginning to think America is more like Ancient Greece than Ancient Rome. The Greeks influenced everything and what followed was this time is known as the Hellenistic Age, but in the end it was Rome which had the thousand year empire. Rome was still quite a bit like the Ancient Greece in its architecture, gods and other trappings, but Romans were not Greeks . I feel history may look back at the American Empire as this shooting star which lit the world while it burned. Everything had been Americanized when it burned out and the "Americanized Age" followed. Unfortunately, America did not lead in this age...if it even survives into it. "Some future history spied in my crystal ball"
