Israel is not much different from any other country, really.
All countries came to existence by stating their claim on the territory and then defending the claim. If there is a country that NEVER had to defend its borders, I don't know any, and would appreciate to be educated on this. (The divorces establishing Czechia, Slovakia, ex-Soviet Republics were peaceful now, but their historical borders were not).
Israel is somewhat unique because its existence was sanctioned by the United Nations in modern times. And we are witnessing history in making that is much different from analyzing historical borders of France, for example. Nevertheless, this experience is only "somewhat" unique, because after the declaring herself, Israel had to prove herself in the old-fashioned way: with arms and blood. Would Israel perish under the joined attack of its Arab neighbors, UN would NOT re-establish her again.
So, Israel earned her existence by defending herself again-and-again and then proved the stake to the land again by creating an oasis of prosperity and agricultural marvel in the destitute inhospitable place. How is it less noble than coming to existence of all other countries? If others suffer historical amnesia and forgot the blood spilled by their own ancestors (rightly or wrongly), it does not change the facts. Like everybody else Israel had to fight to survive and earned her existence.
Also,
The Romans (Italy) were those who named the land of Israel as Palestine when it was under their occupation. So this is just another name to the land of Israel as same as the old name Zion.
