Zionism is, at it's core, the belief in a a Jewish Manifest Destiny, a self-fulfillment of prophecy and of ultra-nationalism. The result is a brutal far-right state, secular in law but theocratic in attitude and with an uncompromising militancy checked only by America and it's (or should I say our) own imperial ambitions. The Zionists (Jewish or Christian, Israeli or Western) like to justify their actions in response to Islamist attacks by Palestinians. Swept under the rug is the Zionist oppression of non-Jews, namely Muslims and Arab/Palestinian Christians (a not-insignificant minority). Zionists claim that they have a right to the land as part of their (long broken they seem to forget) Covenant. While Muslims are displaced to make room for illegal (by Israeli law no less) settlements, Bethlehem, the Mecca of Christianity, has had it's Christian population decimated by Zionist favoritism of Jews and generalizing policy in regards to Palestinians. Arab/Palestinian Jews are no better if not open with their religion and tend to be labeled as traitors if they are yet remain pro-Palestine (never mind that they're Palestinians).
It's a system not universally accepted and openly opposed by a large % of the Israeli population but a lack of Leftist success in elected gov't have prevented this opposition from translating into policy changes. Even the Israeli defeat (by their own admission) in the Israel-Hezbollah War has failed to trigger a policy shift.
Do the Jews have a claim? Yes but so do the Christians, Muslims and to a lesser extent, Bah?'?.
Yes, and Christians, Muslims and Bah?'? are extended full legal rights in Israel proper -- the same rights that are extended to Jews, whether orthodox or not. You or I, regardless of our religious preference, are welcome to worship in any way we please in Israel, and to visit any holy sites (a vast improvement over Muslim or Christian management of that part of the world over the past few centuries), just as we are here in the States, provided that form of worship doesn't include strapping a bomb around our chests and walking into a crowded cafe.
You might want to research your information on the Jewish religious right and so-called Manifest Destiny. Orthodox Judaism opposed the creation of the Jewish state (no messiah, no nation), and in most cases, still opposes the state. Modern Israel was created by secularists. As I suspected would be the case, you're arguing from half a platform.
Also, you really need to look back to 1948, when at the end of the Brit Palestine mandate (at which time the Brits left all territorial armaments to the Arabs, and left the Jews apparently helpless), many thousands of Arabs left the territory, even though they were asked to stay by Jews. The Arab world was, for reasons of its own, unable to absorb those fellow Arabs, and Israel is stuck dealing with them. Research it, and then try to prove me wrong.
Many (not all) of the Arabs in Israeli-occupied territories are interested in destroying, and not much else. Meanwhile, the Jews have been building. Please refer back to my comments on stewardship of the land.
