George Weigel on the weakness of tyranny :

With the benefit of 30 years of hindsight, it now seems clear that the imposition of martial law in Poland in December 1981 was not an act of strength but one of weakness, by a regime so incapable of commanding the allegiance of those in whose name it claimed to rule that it could only compel obedience by violence. It took some time for this to become clear in Poland, a country frequently burdened by crushed hopes; John Paul’s second pastoral pilgrimage to his homeland, in June 1983, did a lot to raise the spirits of his countrymen—who rallied their energies such that, by 1987, the Pope could spend his third pilgrimage home laying the cultural and moral foundations for a post-communist Poland, which was born two years later in the Revolution of 1989.
