For most of the last century, the West faced real enemies: totalitarian, aggressive, armed to the teeth. Between 1918 and 1989, it was possible to believe that liberal democracy was a parenthesis in history, destined to be undone by revolution, ground under by jackboots, or burned like chaff in the fire of the atom bomb.

Twenty years ago today, this threat disappeared. An East German functionary named Günther Schabowski threw open his country’s border crossings, and by nightfall the youth of Germany were dancing atop the Berlin Wall, taking hammers to its graffiti-scarred facade. It was Nov. 9, 1989. The cold war was finished.

There will be speeches and celebrations to mark this anniversary, but not as many as the day deserves. (Barack Obama couldn’t even fit a visit to Berlin into his schedule.) By rights, the Ninth of November should be a holiday across the Western world, celebrated with the kind of pomp and spectacle reserved for our own Independence Day.

Never has liberation come to so many people all at once  to Eastern Europe’s millions, released from decades of bondage; to the world, freed from the shadow of nuclear Armageddon; and to the democratic West, victorious after a century of ideological struggle.
