There's more than four items that support the position of the Israelis, and some of them are:
1. It is their promised land, the land to which they are linked historically and spiritually, the land of their old kingdoms.
2. There was not a country named Palestine or people that defined themselves as Palestinians prior to their return to Israel.
3. They are the dominant population in the country.
4. Israel is considered as a land deserved after the genocide and sufferings that they had during the World War II.
