I wish I could be as certain about THIS part:

I know there are probably more European Jews where you are than anywhere except maybe the UK, and that between the two that is probably 70-80% of ALL European (or at least Western European) Jews. All that said, I still cannot help feeling the Holocaust did not so much wipe out European anti-Semitism as prompt it to export "the Jewish Question" once and for all and count a European anti-Semitic debt going back to Rome paid. In that sense, one could argue Europe was obligated to restore a Jewish nation-state because Europe destroyed it in the FIRST place, for the great crime of demanding independence sought by force when refused.

All that is just an ignorant immigrants impression, yet I cannot shake the strong recurrent feeling that exporting the Jewish Question never expunged Europes anti-Semitism, only prompted support for Palestinians as "anti-Semitism by proxy." One could go blind seeking European leaders denouncing Palestinian terrorism, even at the height of the Cold War, when Israel was a NATO- while Egypt and Syria were Soviet allies regularly and genocidally invading Israel: Even then, Europes NATO-member leaders had naught but condemnation for their own nominal Israeli allies, and excuses for their own nominal (if distant) foes. Maybe after the Munich Olympics—for a few weeks? Still did not justify occupying Gaza and the Golan after the three-nation a few months earlier, right?

That attitude has hardly softened since the Soviet demise removed incentive to support Israel; acknowledgement of Israels rights are ever and always as arguments they entitle Palestinians to the same: Never for Israel itself. Consider that even AFTER the Holocaust, Britain STILL refused to honor its decades-old pledge of an Israeli nation until the political embarrassment of a refugee ship sailing all over the Atlantic rather than accept any home but its own, while Ben Gurions terrorists bombed the King David Hotel to force their hand. After Romes genocidal Diaspora started it all, resulting in two millennia of Inquistion, Blood Libel, Shylocks, Dreyfus Affairs, pogroms, and Pales of Settlement, even the HOLOCAUST was not enough "by itself" to justify Europe restoring the Israeli state it eradicated.

So I do not believe it ended European anti-Semitism; if it had, Israel would have been restored in 1945 rather than 1948, and Europeans would not generally be more sympathetic to a 70-year-old right of return for Palestinians who were never a nation than a 2000-year-old right of return for Israelis who were a nation for centuries.
