Nikolai Krementsov argues that the model of Stalinist science, already taking hold during the thirties, was reversed by the need for inter-Allied cooperation during World War II. Science, as a tool for winning the war and as a diplomatic and propaganda instrument, began to enjoy higher status, better funding, and relative autonomy. Even the reinstated Science Department within the Central Committee was staffed by a leading geneticist and others sympathetic to conventional science. However, the onset of the Cold War led to a campaign for eliminating such servility to the West. Then the Western links that had benefited genetics and other sciences during the war and through 1946 became a liability, and were used by Lysenko and others to turn back to the repressive past and to delegitimate whole research directions.
