Yeah, we've been here before. Empires don't necessarily fall by the hand of their enemies as much as they fall by their own hands and hubris. See: UK, Germany, Russia, historical China and other asian countries, hell even the Romans, and so on and so forth, we've had it all. Trump is nothing new, just another fool in a long line of fools.
It is getting downvoted because it is a well known silly trope. Generally, success reinforces itself. That’s why there have been a bunch of countries that have had multi-generational streaks of repeated success.

Actually, it kind of is.
See The Fourth Turning and any other book based on the Strauss-Howe generational theory.
Is this theory air-tight and inviolable? No. Does it more or less support this “silly trope”? Yes. I think it’s safe to say that it is directionally correct.
If you think that it's just an imagination, the universe will make you physically feel what it really is. Not all at once, but gradually, drop by drop. And then, you'll learn the true meaning of another "meme" word: ignorance.
