Israel's cries of victimhood were already starting to wear thin when it was focused on the Holocaust. Yes, it was a terrible tragedy, but it's 80 years ago at this point - very, very few people are left that were directly involved and the circumstances have changed significantly since then. But going back over five hundred years to try to find "gotchas" is just sad and counterproductive.
People are suffering right now and being persecuted right now, and it has nothing to do with the Inquisition or the Nazis.
