While I understand and sympathize with the plight of the children growing up in the various enclaves of "Palestinians" in the state of Israel, I have no sympathies for the "Palestinians" because they are the cause of their own suffering and the cause of their Children's ongoing suffering.
"Peace in the middle East" is a hopeless fantasy until the Arabs once and for all realize the Jews are there to stay and they are not going to ever be able to kill them all off, conquer them, or drive them out and are willing to renounce violence and murder and be willing to work out a negotiated, peaceable compromise... which we are never going to see them be willing to do in our lifetimes.
The Communists, Progressives and SJW type hate Israel and religious Jews just as bad as the Muslims do, but don't want to get their hands dirty, so they support the "Palestinians", hoping, just as stupidly as the rest of the Arabs, that somehow they can help the Muslims to kill off the Jews and destroy Israel for them. Most of Europe falls into this category also, which is why the UN is firmly and unashamedly hardline anti Israel at every possible opportunity.
What is ironic is that the greatest supporters of Israel and religious Jews, outside of Jews in America of the more Zionist persuasion, tend to be American "red state" patriots, evangelical Christians. (Of course what Israel and the religious Jews privately think about them is best left undiscussed as the truth would lead to being called various hot button names, suffice it to say there is a video online of one of the Israeli prime ministers telling a private family group exactly & truthfully how much power they wield over the politics of (names for you that would offend you) America). It's an interesting dynamic but the long and short of it is, if you as an American travel to Israel, chances are the only danger you face is if some Arab gets you in the cross fire while trying to kill Jews. Compared to most Arab countries where you are one misstep away from being killed or in some hell hole prison.
Now if you head over to Israel with the intention of helping their enemies and those that are trying to kill them and running propaganda operations against them... don't expect them to roll out the red carpet.. you'll just get arrested, expelled and if you happen to be actively helping violent terrorist, may "accidentally" catch a bullet for your trouble and nobody that matters is going to be too sorry for you.
