It has been 30 years since Soviet troops marched and tanks rolled down Wenceslas Square in Czechoslovakia's capital to crush a reform movement known as Prague Spring. Alexander Dubcek's attempts to create "socialism with a human face" are often seen as historical and ideological forerunners to Mikhail Gorbachev's reform policies of glasnost and perestroika in the 1980s in the USSR. The events of 1968 shattered many illusions about Socialism and the Soviet system -- both in Czechoslovakia and in the West.
