Is it true that the majority of Israelis were Europeans who escaped WWII to conquer Palestine (read entirety)?

And why should Israel have to give up its land when the Palestinians are not expected to? You want them to live side by side in the same neighborhoods, but Palestinians do not tolerate Jews to live in their own ones. Jews are being run of of every country in the Middle East, but they're expected to share their own land with people that won't share theirs, and hate them? I don't understand how people can be oblivious to the terrorism that Palestinians have comitted against Israel. BTW, the Israelis did not "conquor" Palestine. They own their land fair and square.
