I havent read the entire discussion, but it seems to me that there are huge portions of this argument missing.
1. According to the rules of modern society (which I don't personally agree with), he who wins the war takes the land. The Brittish empire defeated the Ottoman empire in WWI, and gained the "right" to own the land now known as Palestine from the Ottoman empire. Like it was stated above, what gave the Romans the "right" to take Israel, or the Muslims to take it from the Romans, or the English to take it from the Muslims during the Crusades, Superior Force.
2. The Jews claim the right to to the land because it was the birthplace of their religion. Does that give them a right to it I dunno? What gives anyone the right to do anything for that matter?
3. In reality the Jews were given Israel, because Jewish bankers basically own England due to massive loans given to the state of England going back to the 1500's. If the Jewish Banking system were to stop giving money to the English Governemt the economy would collapse, much like how it is in america now. If the federal reserve (A system of private banks) were to quit giving money to the U.S. Government the economy would collapse. I'm sure the are a fair share of Zionist among the elite Jewish Bankers, and they told England to make Israel a home for the Jews or we quit loaning you money. As a leader of England, do you compromise your entire financial system for a small peice of desert along th Jordan River?
4. The other key concept that I have not seen mentioned is that the Arabian Muslims outcast the Palestinians just as much as the Jews do. When all this started many Palestinians tried to migrate to surrounding Arab countries, and they would not let them come into their countries. Saudi Arabia and Iran would rather "sacrifice" the Palestinians to create conflict in Israel rather than give them safe haven in their own countries in provide peace in the region. Most of the Palestinian terrorist groups are funded by Iran or Saudi Arabia.
5. Last but definitiely not least, the true elite of society could give a **** less about any form of religion or ethnicity. The oil Sheiks of the Middle East, the elite Jewish bankers, the American and European Corporate Tycoons, they are all in cahootz together and don't give a damn about what religion or ethnicity one another are is long as their group maintains control. All they care about is control, and the easisest way to control people is to induce fear. The conflict in the Middle East is an easily controllable way to induce a large amount of fear over the whole world, so why would they help to create peace when it's so easy to let ignorant people fight over stupid ideas that they care nothing about?
