very much so, many years when I was a young boy I met an older Czech man who claimed to have been in the team who beat the soviets in the word championship final after Prague Spring
He said it was pure emotion. Afterwards they were afraid of what the Soviet’s would do to them, and were scared of going back home..
Perhaps worth noting that Czechoslovakia won at home in Prague in 1972 and there was no final at the time. Czechoslovakia did beat the Soviets in 1969 as well, but the Soviets won gold regardless.
