How will France deal with rising anti-Semitism?

Parisians braved blustery winds and returned to the streets this week, not to denounce a spate of terror attacks in recent years, but the older scourge of anti-Semitism that some say is taking on a new, increasingly violent turn.

The sea of protesters Wednesday night included Jews and Muslims, rabbis and school children, who marched shoulder-to-shoulder from the Place de La Nation to the modest apartment where 85-year-old Holocaust survivor Mireille Knoll was stabbed and then burnt last week, in what police believe was an anti-Semitic attack.

For some, the throng amounted to an affirmation of the country’s essential values, unbroken by waves of terrorism and hate crimes. But the march did not necessarily resonate in the gritty suburbs circling the capital and other parts of France, where radical Islam and untended grievances have helped to craft a new, more violent form of anti-Semitism.
