Abstract
Anti-Semitism may be the oldest hatred, but it still comes up with horrifying surprises. One of them is a spike in anti-Semitism, stoked by a President who seems wildly pro-Israel and even has a Jewish daughter. This crazy dynamic climaxed yesterday when 11 Jews were murdered in a synagogue in Pittsburgh. Throughout history people have slaughtered Jews for every reason under the sun. But we still need to attend to their reasons.
