Nine-times Wimbledon champion Martina Navratilova has retaken Czech citizenship, which she lost when she defected from the former Czechoslovakia as an 18-year-old. Although she intends to retain her US citizenship, last year she told a Czech newspaper that she was now as ashamed of George Bush's America as she once was of the communist regime of her homeland. "The thing is, we elected Bush," she said. "That is worse! Against that, nobody chose a communist government in Czechoslovakia."

Strong words, but can one really compare the Czechoslovakia of 1975 with the United States of today?

Czechoslovakia, 1975: Despite widespread discontent with the oppressive Husak regime, a 1974 study finds active support for the government in 15% of the population, identified as pensioners, party bureaucrats, careerists, "parasites", extremist ideologues and persons involved in the Stalinist repression who fear that liberalisation might force them to account for their crimes.
