Here is Philip Henscher, writing in The Spectator (in a review of Volume 2 of Charles Moore’s biography of Mrs Thatcher):
“There is no question that Mrs Thatcher, by boldness and conviction, in large part initiated the process that brought freedom to millions in Eastern Europe.”
This is nonsense. The denizens of Eastern Europe were bravely and publicly protesting their confinement from the late 1940s, at a time when Mrs Thatcher was so junior she was still a chemist. The actual liberation of the Comecon countries began in Poland in the 1950s (and again in the 60s and 70s and 80s), in Hungary in the 1950s and 60s, in the CSSR in the mid 1960s, and the USSR in the 1950s under Khrushchev, and the 1980s, under Andropov. Mikhail Gorbachev was a brave member of the verligte wing of the CPSU, but he was not the first to seek to reform communism, not even in the USSR.
Gorbachev was university friends in the 1950s with Zdenek Mlynar, later one of the architects of the Prague Spring, which Gorbachev followed closely. See here. It is ridiculous to imagine that it took a weekend lunch with Mrs Thatcher at Chequers to persuade him to embark on reform. What next? Did she also invent the Internet? That her supporters should seek to award Mrs Thatcher the credit for the downfall of communism is also insulting to the brave people who did initiate the changes, and who, with their courageous actions, brought them about.
