Even the Jews didn't establish Jerusalem. It was before David's time known as Jebus, and the residents were Jebusites until David conquered them and took the city for his new capital (His old capital was Hebron) because of its strategic position..............
Well, you're correct about that. I guess that's so far back we don't have any feeling for it (maybe the Pali's don't, either).
In any case, it's another good lesson that "conquering" ALWAYS happens and has happened to every (just about) population, regardless of race, religion, size, anything. To try to rectify everything back to its original point would be nothing short of ludicrous. So whining about ancient "siezures" really is moot, esp. when the whiner's ancestors probably also "seized" it from someone ELSE.
