Soviet Army soldiers sit on their tanks in front of the Czechoslovak Radio station building in central Prague during the first day of Soviet-led invasion to then Czechoslovakia August 21, 1968. Vera Machutova woke one August night in 1968 to the thunder of Soviet tanks surging through this Czech city on the East German frontier. Forty years later, with the Czech Republic now a democracy within NATO and the European Union, Machutova is troubled by the conflict in Georgia, whose army was routed last week by Russian forces that pushed deep inside its territory.
