I think that it is really wrong that the palistine people would go against what was promised to other people from God. I read, in the link that God made a promise to Abraham about the land. The other country should respecet that.
I think that they deserve the land, because it was rightfully theirs at first, before war and everything terrible happened. After that the other people came in and took their land over! (Which wasn't very nice. >:() So because of them invading their space, they started forcefully fighting to get it back.
