And yet once again, the same vile racism that led to the Holocaust burbles and blazes right across Europe. Once again Jews (and in an updated twist, the Jewish state) are blamed for just about every evil of the age from the world's economic woes to an al-Qaeda atrocity.
The neo-Nazi football fans of the Ukraine taunt each other with cries of 'Jews!' not because members of the other team are actually Jewish, but because that's about the worst insult they can think to hurl.
The leftie Jew-haters who believe themselves more sophisticated in their sneaking anti-Semitism single out Israel, the Jewish state, as the world's Great Satan. On the right, Jew-hating is fanatical; on the left, it's fashionable.
But right across this spectrum of venom and prejudice runs the old libel - it's all a 'Jew job'.
If you were Jewish in Europe today, knowing all that's gone before and knowing what is always possible again, wouldn't you too be fearful of the writing on the wall?
... right now and it won't take much for them to go back to their old ways. It can be argued that the old ways never actually went away it just became temporarily unfashionable to express them openly.
If the economic situation in Europe deteriorates to a full-fledged depression, you will see (we already are seeing) radical left and radical right parties gaining more power and looking for ethnic scapegoats.
Will this affect the Jews of Europe again? Definitely. Many will have to leave and lose their homes and possessions. Will there be another Jewish Holocaust? Doubtful. Jews of today aren't the Jews of the "thirties". There are fewer of them, they aren't in denial of just how terrible things can get and they have a land to go if things become too bad.
I have no doubt if things go to shite in Europe, they will start looking for minorities to pack into boxcars again only, at least this time, it won't be the Jews. I just hope and pray it won't come to that for the minorities that end up becoming the target of European's wrath this time.
