Dr. Leff gave a talk on April 21 about the Warsaw Pact invasion of 1968 and the impact of Czechoslovak institutional relations. She discussed the federalization that survived the Prague Spring and how it influenced events in 1989 and the Velvet Divorce. Dr. Leff also talked about the roles of Dubček, Husák, and Biľak in the failure of the “Socialism with a human face” policy. She speculated on whether the Soviets would have tolerated any substantial reform effort. The lecture was well-attended and was co-sponsored by Friends of Slovakia and The Slovak American Society of Washington, D.C.
