became "subjects of the state"). It instituted a pogrom on the night of 9–10 November 1938, dubbed Kristallnacht, in which Jews were killed, their property destroyed and their synagogues torched. Antisemitic laws, agitation and propaganda were extended to German-occupied Europe in the wake of conquest, often building on local antisemitic traditions. In 1940, the famous aviator Charles Lindbergh and many prominent Americans led the America First Committee in opposing any involvement in a European war. Lindbergh alleged that Jews were pushing America to go to war against Germany. Lindbergh adamantly denied being antisemitic, and yet he refers numerous times in his private writings – his letters and diary – to Jewish control of the media being used to pressure the U.S. to get involved in the European war. In one diary entry in November 1938, he responded to Kristallnacht by writing "I do not understand these riots on the part of the Germans. ... They have undoubtedly had a difficult Jewish problem, but why is it necessary to handle it so unreasonably?", acknowledgement on Lindbergh's part that he agreed with the Nazis that Germany had a "Jewish problem".

In the east the Third Reich forced Jews into ghettos in Warsaw, in Kraków, in Lvov, in Lublin and in Radom. After the beginning of the war between Nazi Germany and the Soviet Union in 1941, a campaign of mass murder, conducted by the Einsatzgruppen, culminated from 1942 to 1945 in systematic genocide: the Holocaust. Eleven million Jews were targeted for extermination by the Nazis, and some six million were eventually killed. Contemporary antisemitism Post-WWII antisemitism There have continued to be antisemitic incidents since WWII, some of which had been state-sponsored. In the Soviet Union, antisemitism has been used as an instrument for settling personal conflicts starting with the conflict between Joseph Stalin and Leon Trotsky and continuing through numerous conspiracy theories spread by official propaganda. Antisemitism in the USSR reached new heights after 1948 during the campaign against the "rootless cosmopolitan" (euphemism for "Jew") in which numerous Yiddish-language poets, writers, painters, and sculptors were killed or arrested. This culminated in the so-called Doctors' Plot in 1952. Similar antisemitic
