Pooter, your butterflies could at the end permit a very early end of the cold war, with Czechoslovakia not a soviet satellite it is possible that the soviet leaders after the death of Stalin in 1953 (or 1952 or 1954 if this is butterflied by the events of this Timeline) decides with more force to offer the West a pact for end the division of Europe, in OTL Beria and Malenkov clearly go to the path to end effectively the cold war, even Beria thinkings were to permit the reunification of Germany in exchange of being Germany a neutral country, in fact Beria clearly seemed think in finlandize Eastern Europe more than in maintaining it as a Soviet protectorate making possible radical changes in all Communist countries to permit more liberalization.
Truly with a Czechoslovakia aligned with the West the need to end the Cold War in Europe for the new alternate leadership could be more strong than in OTL.
