Explanation:

Czechoslovakia was not among the five unaligned European states because it was part of the Soviet sphere of power. By 1980, Czechoslovakia was ruled by the Communist Pary, and the General Secretariat was Gustáv Husák.

In fact, eleven years before, in 1968, the country had experienced the Prague Spring, in which thousands of people marched in Prague asking for more political and civil rights. This movement ended when the Soviet Army invaded Prague with tanks.
