After the Second World War, the attitude towards Jews in the USSR changed dramatically as compared to the interwar period. Until then, the Jewish people had been regarded as a “loyal” minority without a conceivable homeland outside the USSR. (Although as far back as the mid-1930s they were unofficially squeezed out of the administration higher-ups, with an opportunity left for them to pursue careers in the fields of science and culture). However, after the proclamation of the State of Israel in 1948, the Communist party leadership and security services began regarding Soviet Jews, who were cultural professionals, worked at universities or medical institutions, as being a threat. In the territories that had undergone Nazi occupation during the war, this attitude was further intensified by the consequences of three years-long exerting ideological influence of outright anti-Semitic propaganda upon the local population.
