In 1998, Ignatz Bubis, a leader of the German Jewish community, pointed to a "spreading intellectual nationalism" that made him fear a revival of German antisemitism. Others point to Germany's growing Muslim population, both the Turkish "guest workers" who began to arrive in the 1950s, and the large wave of migrants from the Muslim countries who arrive during the European migrant crisis that began in 2015. In 2002, the historian Julius Schoeps said that "resolutions by the German parliament to reject antisemitism are drivel of the worst kind" and "all those ineffective actions are presented to the world as a strong defense against the charge of antisemitism. The truth is: no one is really interested in these matters. No one really cares."
