Photos of the burning of a homemade Israeli flag by Muslim demonstrators in Berlin in December 2017 drew international attention due to their association with images of Nazi book burnings in 1933. Senior German politicians have exposed widespread anti-Semitism among the country’s Muslims, a situation borne out by various studies. While measures have been announced against Muslim anti-Semitism, the most important action has not been proposed: to screen all those wanting to immigrate for anti-Semitic and anti-Israel attitudes and bar those found to hold such beliefs.
