We have entered an age of insecurity—economic insecurity, physical insecurity, political insecurity. The fact that we are largely unaware of this is … - Tony Judt

In the short run the Soviet authorities and their colleagues in eastern Europe could certainly suppress easily enough any voices raised on behalf of individual or collective rights: in 1977 the leaders of a Ukrainian ‘Helsinki Rights’ group were arrested and sentenced to terms ranging from three to fifteen years. But the very emphasis that Communist leaders had placed upon ‘Helsinki’ as the source of their regimes’ international legitimacy would now come to haunt them: by invoking Moscow’s own recent commitments, critics (at home and abroad) could now bring public pressure to bear on the Soviet regimes. Against this sort of opposition, violent repression was not just ineffective but, to the extent that it was public knowledge, self-defeating. Hoist by the petard of their own cynicism, Leonid Brezhnev and his colleagues had inadvertently opened a breach in their own defenses. Against all expectation, it was to prove mortal.

The war changed everything. East of the Elbe, the Soviets and their local representatives inherited a sub-continent where a radical break with the past had already taken place. What was not utterly discredited was irretrievably damaged. Exiled governments from Oslo, Brussels or the Hague could return from London and hope to take up the legitimate authority they had been forced to relinquish in 1940. But the old rulers of Bucharest and Sofia, Warsaw, Budapest and even Prague had no future: their world had been swept aside by the Nazis' transformative violence. It remained only to decide the political shape of the new order that must now replace the unrecoverable past.

Lenin’s distinctive contribution to European history had been to kidnap the centrifugal political heritage of European radicalism and channel it into power through an innovative system of monopolized control: unhesitatingly gathered and forcefully retained in one place. The Communist system might corrode indefinitely at the periphery; but the initiative for its final collapse could only come from the centre. In the story of Communism’s demise, the remarkable flowering in Prague or Warsaw of a new kind of opposition was only the end of the beginning. The emergence of a new kind of leadership in Moscow itself, however, was to be the beginning of the end.
