Former Czechoslovak Communist party ideology chief Vasil Bilak, the last
surviving hardliner who sent a letter of invitation to Soviet leaders,
officially justifying the Warsaw Pact invasion that crushed the Prague
Spring reform movement in 1968, has died in Bratislava at the age of 96.
Bilak was charged with high treason in 1991 but the case was later closed
for lack of evidence. I asked prof. Jan Rychlik, who specializes in
Czechoslovak history, how Vasil Bilak will be remembered.
