The Israeli's obviously have a better army because they keep fighting for the land and keep winning. I found death rates in Palestinians are MUCH higher than Israeli's. I think to keep a country stong you need people to live longer.
I agree, the Israeli's had permission to take the land, not just attacking and taking over.
Read the third through seventh paragraphs on the following link - speech from United Nations, granting the Jews the land.
I think the Israeli's deserve the land because in the bible, it says God promised the Jews the land as a homeland. Most of the Jews beleive this so most of the Jewish population is in Israel. The Palestinians have no promise to any land, so they mostly live in the West Bank, the Gaza strip, and Jordan.
