This week’s visit by Hungarian Prime Minister Gordon Banjai is an excellent opportunity to focus on one of the most important and interesting cases of a Nazi war criminal who can still be brought to justice. I am referring to Dr. Sandor Kepiro, who served as a gendarmerie officer during World War II and was among the key organizers of the mass murder of at least 1,250, but probably as many as 3,000 men, women and children (mostly Jews, but also Serbs and Gypsies) in the Serbian city of Novi Sad on January 23, 1942.

Until now, Israel has done relatively little to press Hungary to prosecute Kepiro, so Banjai’s visit might well be the last opportunity of its kind for the government to send a clear-cut message to the Hungarians that their failure to bring Kepiro to justice is incomprehensible and unacceptable.
