Actually, Ceaucescu, Romania's dictator at that time, hated Stalin and his regime. I don't know about the GDR and other countries but being born under Ceaucescu's regime, I can tell you that Romania had nothing to do with the USSR other than it being a trade partner of some sort.
Romania is one of the few countries in Europe to excist in it's current form as an independant country for a long long time. We never had foreign rulers, not even as satellites. We overthrew our dictator in November 1989 where the Soviet Union, to my knowledge, overthrew itself. Quite some differences in the histories of those countries.
