The great moment when the Berlin Wall fell was an era when two great bastions of tyranny fell - most of the Communist states, and most of the Latin American capitalist authoritarian states. The world is a freer, richer, and more peaceful place because of those two great revolutions.
They were revolutions not just of one nation or another, but of many nations suffering under similar ideological regimes. The several revolutions fed off one another as they rose up. And, just as important, those ideological regimes lost heart, lost faith in their own legitimacy. The continuous pressure and example from the democracies was vital to both encourage the people and discourage the regimes. The democracies, the United States included, have many faults and mixed motives, and we also supported many of those oppressive regimes for a long time. But in that glorious moment, the good causes and good reasons came together.
The Muslim states are the last major bastion of ideological authoritarianism on earth today. We are witnessing a similar combination of happy forces against that ideology. There are sufficient pro-democracy populations in most Muslim nations to rise up, and to rise up with amazing discipline. The ideology that authoritarianism is a Muslim value is tottering, and is being opposed by Muslim intellectuals, journalists, and some religious leaders. And the democracies seem willing, even eager, to support democratic regimes in Muslim nations - even the ones with oil.
The news of the next few months will no doubt bring blood and horror, as some regimes - the Libyan, for example - fight back with brutal oppression. And we do not know what kind of regime Egypt will end up with. After the Wall fell, after all, the Russians gave up their empire, but the Chinese did massacre their democrats at Tienanmen Square. Some tyrannies will win this round, and some oppressed people will not even try to rise up.
I believe that when the dust settles, though, there will be, say, half a dozen Muslim democracies, and a several less oppressive Muslim regimes. Most importantly, the connection between Islam and authoritarian ideology will be broken.
