Many empires have fallen, so some current or future empires will also fall. Entire civilizations were extinguished, so it will be the same in the future.

They say that it is best to learn from the example of others, but somehow a person learns best when he does it on his own example, feels it on his own skin.
But as a person tends to suppress or forget some ugly things from his past, it is quite possible that he will make the same mistake in the future. If something like that happens, if he repeats a mistake from the past, then there are only two possible reasons... Either he likes what he repeated (and got hurt because of it) or is he just stupid?
