Another feature of Husák's rule was a continued dependence on the Soviet Union. As of the mid-1980s, Husák had not yet achieved a balance between what could be perceived as Czechoslovak national interest and Soviet dictate. In foreign policy, Czechoslovakia parroted every utterance of the Soviet position. Frequent contacts between the Soviet and Czechoslovak communist parties and governments made certain that the Soviet position on any issue was both understood and followed. The Soviets continued to exert control over Czechoslovak internal affairs, including oversight over the police and security apparatus. Five Soviet ground divisions and two air divisions had become a permanent fixture, while the Czechoslovak military was further integrated into the Warsaw Pact. In the 1980s, approximately 50% of Czechoslovakia's foreign trade was with the Soviet Union, and almost 80% was with communist countries. There were constant exhortations about further cooperation and integration between the Soviet Union and Czechoslovakia in industry, science, technology, consumer goods, and agriculture. Deriving its legitimacy from Moscow, the Husák regime remained a slavish imitator of political, cultural, and economic trends emanating from Moscow.
