In case you missed this last week: Haïm Korsia, the recently elected chief rabbi of France, used the occasion of an event commemmorating Holocaust victims to call for solidarity with religious minorities in the Middle East:

The situation of religious minorities all over the world and especially in the Middle East resonates, unfortunately, with our commemoration today. . . As our parents wore the yellow star, Christians are made to wear the scarlet letter of ‘nun.’

Korsia specifically cited the plight of the Yazidis, too. He also may well have in mind the security of the region's Jews. But by explicitly comparing the yellow star with the mark of the Nazarene, he made a provocative suggestion: Middle Eastern Christians are to ISIS what European Jews were to the Nazis, namely a primary (though not the only) target of a horrifying, genocidal violence. And this fact alone demands the world's solidarity.
