I've seen on the Internet recently that Palestine or a close spelling of it came from the Romans who named the territory after former occupations, and Palestine is how the Romans spelled Philistines or a close spelling of those people.
Ok I know what your doing now, your rolling your eyes like I did at first, but you got to admit it sounds like a good argument, and the philistines were a former occupant of the land before the Jews, and the Romans only existed maybe one century or two after they killed a majority of Jews in Judah and destroyed Jerusalem and the temple of the Jews.
For the record the Romans wanted to save the temple as it was one of the wonders of the world, but as many things happen unexpectedly in the fog of war it got set on fire by a torch and burned to the ground.
No one really knows who set it on fire, but there was a attempt to put it out but that failed. This all happen around A.D. 70
I found this recently, though have not had the time to view it:
History of Israel-Palestine Conflict
The Romans renamed the region of Judæa (named for the Jews and the patriarch Judah) as “Palæstina” (after the Philistines), circa 135 AD when they merged it with Syria thus creating “Syria-Palæstina”.
I do not know where you got that “fog of war” story from, but if the Romans really wanted to save the Second Temple and not utterly destroy it, that’s what they would have done.
