When I post news reports about European mujahideen who travel to the Middle East to join the jihad, I often refer to their nationality in scare quotes, because they are as much Germans or Dutchmen as I am a Hottentot. However, in this case no quote marks are warranted — the late mujahid Thijs Belmonte really was Dutch. He converted to Islam in 2005 and pursued his religious vocation by beheading infidels in Syria.
