During the Cold War, Western nations, particularly the United States, were very wary of Soviet aggression toward other European nations. This was the case after World War II when Stalin brought Eastern European countries into the Communist fold. When these countries began to revolt, however, the concern of Western nations only increased. When Hungary and Czechoslovakia revolted at the height of the Cold War - 1956 and 1968 respectively - tensions between the West and the Soviet Union was at its highest point. The fear that the Soviet Union sought to repeat the Hitler's program of aggression still lingered, and the Soviet Union's attempts to maintain control over its satellite states only served to confirm their fears. Nations in the West hoped that these countries, should they extricate themselves from Soviet control, could serve as examples for those nations still under Soviet influence. When Poland revolted in 1989, the situation in the Cold War was much different; the tensions that had fueled the Cold War had begun to wane. That being said, Western nations still harbored the same fears and perceived Soviet intervention as a show of aggression. As with Hungary and Czechoslovakia before, the United States hoped Poland would slough off Soviet control.
