While Islamic State (IS) jihadists battle their way across Syria and Iraq, beheading soldiers and civilians, training children for jihad, their supporters across Europe demand "death to Jews" and call for the blood of infidels.
Now, it seems, some European leaders are refusing to fight back.
The situation has become especially controversial in the Dutch political capital of The Hague, where pro-IS protests in July involved anti-Jewish chants and a violent attack on a female journalist covering the event. As the Jew-hate worsened and violence intensified, witnesses and Jewish advocacy groups called on the mayor's office to step in. But Mayor Josias van Aartsen was on holiday; and his deputy, left in charge, found no reason to intervene.
