"Tyrants had been around for thousands of years; but George Orwell's great fear, while writing 1984 on his lonely island in 1948, was that the progress made in restraining them in the 18th and 19th centuries had been reversed. Despite the defeats of Nazi Germany and Imperial Japan, it would have been hard to explain the first half of the 20th century without concluding that the currents of history had come to favor authoritarian politics and collectivist economics. Like Irish monks at the edge of their medieval world, Orwell at the edge of his was seeking to preserve what little was left of civilization by showing what a victory of the barbarians would mean. Big Brothers controlled the Soviet Union, China, and half of Europe by the time 1984 came out. It would have been Utopian to expect that they would stop there. But they did: the historical currents during the second half of the 20th century turned decisively against communism. Orwell himself had something to do with this: his anguished writings, together with the later and increasingly self-confident ones of Solzhenitsyn, Sakharov, Havel, and the future pope Karol Wojtyla, advanced a moral and spiritual critique of Marxism-Leninism for which it had no answer. It took time for these sails to catch wind and for these rudders to take hold, but by the late 1970s they had begun to do so. John Paul II and the other actor-leaders of the 1980s then set the course. The most inspirational alternatives the Soviet Union could muster were Leonid Brezhnev, Yuri Andropov, and Konstantin Chernenko, a clear sign that dictatorships were not what they once had been."
