Just silly and not an apt comparison at all. A more apt comparison would be should the UN or the USA take part of Nigeria for instance , ethnically cleanse the local folks out of huge areas of it and give it to African Americans, Afro Caribenos, Afro Brazilians and any other group that descends form African slaves who would then have the "right to return", but not the recently ethnically cleansed folks.. WRT to Palestine/Israel we are talking about ethnically cleansing the people who lived there when the Euro colonialists (who happened to be Jews). It would be just as wrong to take Muslims living in say Istanbul and ethnically cleanse the local people and move them in.
Like I said earlier: no one is prepared to deal with the consequences of expensive and less abundant Saudi oil. And I don't think the Saudis are ethnically cleansing anyone. Boko Haram on the other hand may be.
The Palestinians were born in the homes they were forced out of. It's the Israelis who illegally took their houses and are occupied them. So you are saying that the Palestinians have a right to take their homeland back. Interesting.
Who are given no rights and are prevented from leaving their reservation and surrounded by barbed wire, and not allowed to even have an airport. Also they would be under a blockade. That wouldn't be allowed in the U.S. We believe in human rights. Many people in Germany do too. Too bad you don't.
And how much to Egypt, Jordan, Germany, Colombia, Korea, UK, Mexico, Japan, Saudi, etc.... Just for comparative purposes.
