I was truly shocked to learn about the terrorist attack in Vienna. Such Europe on Europe attacks, this time by a lone Macedonian gunman owing allegiance to the purported leader of the ISIL, Abu Ibrahim al-Hashimi al-Qurashi, is even more a matter of concern. Clearly this manifestation of jihadi terrorism is indicative of some great societal failure. That it happened so close to your institution but missed it is truly providential. Please convey my concern to Dr. Schwimmer. My best wishes to you as always.
