Prague Spring crushed
21 Aug 1968 — Half a million Warsaw Pact troops end Czechoslovakia’s “socialism with a human face.” The Brezhnev Doctrine is born: fraternal states may never leave. 1989 is its exact negation.
THE MOMENT IN CONTEXT
Mikhail Gorbachev inherits, in March 1985, a superpower in slow-motion failure: growth near zero, a defense burden triple America’s share of a far smaller economy, life expectancy falling, a Politburo whose last three leaders died in office within thirty months. His program — perestroika (restructuring) and glasnost (openness) — aims to save socialism, not bury it. Then Chernobyl explodes in April 1986, and the cover-up’s collapse radicalizes glasnost into something no Soviet leader had permitted: actual truth, compounding. Abroad, Gorbachev moves faster than the West can process: at Reykjavík he and Reagan improvise to the edge of abolishing nuclear weapons entirely (the marker in the far northwest); the INF Treaty (1987) eliminates an entire missile class — the first arms reduction of the age; and in December 1988 at the UN he renounces the Brezhnev Doctrine outright, cutting 500,000 troops. His spokesman later jokes that satellites now enjoy the “Sinatra Doctrine”: they do it their way.
