I know that it is difficult for you to understand so I'll write this slowly. The Jews are the natives in this land. Not the Palestinians. I suppose things would be simpler for you to understand if it was the Arabs who destroyed the Jewish Temple in 70AD, but it was the Romans. This was the land of the Jews before this event. The Romans forced the Jews to leave (not all though). We have now returned and this new nation called Palestine, who have never ever ruled in Jerusalem even for one day, needs to reconcile with Jewish history and find a place for both Muslim and Jew.
