The right of return, to Poland

On C-Span, I just caught a portion of Trinity Professor Samuel Kassow's recent lecture at the Tenement Museum in New York on the Warsaw ghetto archives that were somehow preserved through the Holocaust. Kassow has written a book called, Who Will Write Our History? Most of Kassow's talk was historical. He said that even dying, Jews understood they were part of an Ashkenazi Jewish "nation" whose ways must be preserved. He said that many Americans know this history from reading John Hersey's The Wall.
Someone asked about the Jewish life of Warsaw now, and Kassow said it was flourishing, but in a very small way. I think I heard him say it is about 5000 identified members, with about 20,000 others of Jewish heritage.
Then Kassow said that in Israel, you see long lines of Israelis at the Polish embassy, seeking visas to go to Poland so they can work "in the EU." Poland is Israel's best friend in Europe, he continued. There is none of the "mishigos" or "hysteria" that you find in, say, France, about Israel's behavior.
He was talking about the Gaza slaughter, obviously, in which an enclosed population was lately bombed and assaulted, and 412 children were killed, leading some non-Zionist Jews to compare Gaza to the Warsaw ghetto.
A few questions:
How imprisoned are we Jews by our history? Can we see the facts before our eyes? Does it mean anything that Kassow, a Zionist evidently, teaches at an American college with a strong Episcopalian tradition that blossomed into universalism in the last century? What is to be made of what John Mearsheimer often describes as "reverse aliyah," the demonstrated preference of many Israelis to live in the west, notwithstanding the disturbing history of antisemitism in the west? Does it mean that Israel/Palestine is not of the west? And what is to be made of the desire of hundreds of thousands of Palestinians to return to the land, or maybe even visit it, from which they were expelled 60 years ago, or exiled from by the creation of The Wall, more recently?
(Finally, Sunday bonus question, the only question that American Jews really ought to consider: what does it mean that the most powerful man in Israel today (for he possesses the swing vote) is a racist who moved to Israel from Russia under the "law of return" and now suggests that if he had his druthers he would expel hundreds of thousands of people of a different race and religion from himself whose ancestors have been living there for a long long time?)
