Thousands of British Muslims and Muslim immigrants marched through London on Thursday, chanting, “Jews, remember Khaybar. The Army of Muhammad is coming to kill you, too.” Khaybar, of course, was the site of a massacre of a Jewish tribe conducted by the Prophet Muhammad.

While British Prime Minister Keir Starmer cracks down on speech critical of immigration, he ignores the threat the United Kingdom’s Jews now face. British commentators and human rights advocates rationalize violence against synagogues as understandable given Israeli policies. This is equivalent to burning a church because of disagreement with Italy or vandalizing a mosque in protest of Saudi Arabia.
