The importance of the communist movement in the Soviet Union was demonstrated once again by the international conference of communist parties held in Moscow in June, 1969. To be sure, Soviet foreign policy decisions have always been made on the basis of pragmatic calculations of state interest. Ideology, moreover, does appear to be waning as a motive force on the Soviet domestic scene. Nevertheless, the Soviet Union has maintained a deep commitment to the institutions and forms of the communist movement which go back to Lenin's time, a time which has become glorified, and grossly simplified in Soviet literature as a period of heroic victories. The convictions and institutions of this period have become hallowed: and today Moscow regards the preservation of their forms, if not their substance, as vital if further progress is to be achieved by communism in the international sphere.
