That order is now being challenged, first by violent fanatics who claim to speak for Islam, more recently by autocrats in foreign capitals who see free markets and open democracies and civil society itself as a threat to their power. The peril each poses to our democracy is more far-reaching than a car bomb or a missile. They represent the fear of change; the fear of people who look or speak or pray differently; a contempt for the rule of law that holds leaders accountable; an intolerance of dissent and free thought; a belief that the sword or the gun or the bomb or the propaganda machine is the ultimate arbiter of what's true and what's right.
