Roger Cohen is a bit late to have noticed this, but glad he wrote this fine column. I have relatives who suffer from what he calls “anti-Zionism derangement syndrome.” But as my late brother — who was far too smart to suffer from it — used to say, you can’t reason with people who have this affliction, as they have no interest in facts. Sadly, I am not surprised that much of this derangement has flourished in academia. (Occasionally, I consider going back to school to get my PhD, but then I talk to friends of mine working in academia and reconsider.)

What is striking about the anti-Zionism derangement syndrome that spills over into anti-Semitism is its ahistorical nature. It denies the long Jewish presence in, and bond with, the Holy Land. It disregards the fundamental link between murderous European anti-Semitism and the decision of surviving Jews to embrace Zionism in the conviction that only a Jewish homeland could keep them safe. It dismisses the legal basis for the modern Jewish state in United Nations Resolution 181 of 1947. This was not “colonialism” but the post-Holocaust will of the world: Arab armies went to war against it and lost.

So simple, really. I don’t understand the difficulty people have grasping this, but I think Bernard Lewis was right when he called anti-Semitism a pathology, a mental illness. It isn’t rational.
