They Israelis won many wars for the land, just because someone put them their in the first place doesn't mean they couldn't support themselves. It just means that other peopl thought it would be a good place for them.
What did the Palestinians do that the Jews didn't? Also, practicing the religion there means nothing. You can practice religion anywhere, it doesn't make the land holy or anything.
It has been proven that Israelis were there first. Also, what makes the Palestinians deserve the land? The Jews had nowhere to go either, so it is a weak argument to say that the Palestinians had no where to go.
The Palestinians have practiced their religion there, so what? People have practiced their religion in many places all over the world. Christianity is a well practiced religion in Rome. Does this mean that Rome belongs to Christians only?
Jerusalem has been important to the Jews for a LONG time. It is biblical holy land. Palestine is never mentioned in the Koran, so why is that an argument for the Palestinians?
The Israelis have taken more of the land because they were attacked by the Palestinian people and Egypt. You can't hardly blame them for attacking when the Palestinians attacked first.
