In February 1987, the Politburo of the Central Committee of the Soviet Communist Party â the supreme political authority in the Soviet Union â sought to address the ever-growing vocal support in the international community for the independence of the Baltic republics (Lithuania, Latvia, and Estonia). The resulting Politburo decree, titled âOn the Measures for Counteracting Ideological Diversions against the Soviet Baltic Republics,â was summarized for the KGB of the Lithuanian Soviet Socialist Republic by Lt. Colonel Vilius P. Kontrimas, deputy chief of the First Department (foreign intelligence) on March 24, 1987.
