Daniel: Prophesy after the fact or universal lessons?

In 2022, Vladimir Putin did what ancient kings in the Old Testament did: he invaded another nation - and he did it on his own. We look at the Book of Daniel, and how it proports to be about the Babylonian exilic period, but perhaps was written hundreds of years later, when the Jews were fighting the Greek speaking Seleucids. We look at this book and ask the question: Is Daniel simply a prophesy after the fact, or is it something that we should take in a more general context? Was Daniel doing something wrong if he claimed to be writing about a much earlier period, but was doing it for a faith-based reason?
