You should understand one thing and it will make you life much easier - the world does not run on justice and it never has and never will. If you are trying to determine if justice was made or not with the Palestinians we can go in circles until eternity. There was a certain reality and it changed and each step the Zionist movement made the right decisions and the Palestinians constantly took the most damaging ones.
Now, as for immigration, again, nobody asked the locals because no one ever asked anywhere in the world before, this was colonial time, before that you had empires, who cared what few people think. For example the Ottomans brought all kinds of immigrants into Palestine and did not ask the locals what they think, they even allowed Westerns to settle in - like the German Temple order - without any permission of any local. This were the times and you try to judge those times on 21 century scale.
As for your question, it is not a question of right or justice or what is allowed or not allowed. This was an historic circumvent with certain factors and the Zionist Movement used it to help its people who were prosecuted in East and Central Europe. If a greater power will occupy Israel and decide to build there alternative nation of course I object to it, but unlike the Palestinians I will try to save what I can and not object any proposal and any compromise.
Now, as I said the Jews were already living in Palestine in significant numbers and were a majority of the residence in Jerusalem before the British mandate. And the Zionist movement rejected any plan to establish a Jewish state outside the Jewish historic homeland - after all Zion means the land of Israel.
Your words are clearly saying that Israel was created due to absence of justice.
And about the last few lines, no, actually there were many other proposals for other certain areas, for example the Uganda proposal.
About the Jews population, no, the Jews were never such a majority in Palestine before WW1! The wave of immigrants made you that much, nothing more.
Israeli Arabs have a higher standard of living than many comparable nations. Supporting palestinian terrorists is akin to supporting Afghan taliban, pakistani taliban, chechen terrorists, Kashmir terrorists and Xinxiang terrorists. Here, people mostly show hypocrisy when they denounce pakistan taliban who bombs innocents, however they adore the palestinian terrorists at the same time.
Israel shows remarkable restraint with these terror groups which should be praised. Israel is even prepared to make generous peace proposals with these terrorists.
Terrorists? What terrorists? Has it come now that anyone who is defending their land is terrorist? So what should they do, see the Palestinian land be stolen by endless settlements and their people being killed and shut up?
Don't get me wrong, I'm not with killing civilians or children AT ALL, I'm just asking you to tell me what Palestinians should do, when they see themselves losing their lands by settlers and the creation of a Palestinian state becoming more and more impossible.
For your information, if Israel is fighting " terrorists " of Hamas, who exist only in Gaza, why do Israelis every now and then arrest people in the West Bank?
Also, this amazing country you're speaking about, has discrimination. Al Aqsa Mosque! Nobody ever replied to my question about it. Why shall the Israelis break into Al Aqsa mosque every now and then? What gives them the right to? They break into it under the escort of Israeli security!
About those " generous " offers, do you even know Israel's conditions for the establishment of a Palestinian state? They want it demilitarized ( yeah, as if Israel is no threat to Palestine ), they want control over Palestinian air space, control over all entering and going out people and cargo, control over radio, tv... and other conditions that make Palestine effectively not a state.
What remarkable restraint? Does remarkable restraint represent to you bombing hospitals and homes? Bombing areas where those " terrorists " are known not to exist in?!
Why doesn't anybody remember that Israel is LEGALLY an occupier!? They occupy West Bank, East Jerusalem, Golan heights and Sheba farms. Why doesn't anybody say something about that?
