From Fareed Zakaria in Foreign Affairs from 1997, The Rise of Illiberal Democracy:
(this may require registration to read the whole article which I encourage. )
Illiberal democracies gain legitimacy, and thus strength, from the fact that they are reasonably democratic. Conversely, the greatest danger that illiberal democracy poses — other than to its own people — is that it will discredit liberal democracy itself, casting a shadow on democratic governance. This would not be unprecedented. Every wave of democracy has been followed by setbacks in which the system was seen as inadequate and new alternatives were sought by ambitious leaders and restless masses. The last such period of disenchantment, in Europe during the interwar years, was seized upon by demagogues, many of whom were initially popular and even elected. Today, in the face of a spreading virus of illiberalism, the most useful role that the international community, and most importantly the United States, can play is — instead of searching for new lands to democratize and new places to hold elections — to consolidate democracy where it has taken root and to encourage the gradual development of constitutional liberalism across the globe. Democracy without constitutional liberalism is not simply inadequate, but dangerous, bringing with it the erosion of liberty, the abuse of power, ethnic divisions, and even war. Eighty years ago, Woodrow Wilson took America into the twentieth century with a challenge, to make the world safe for democracy. As we approach the next century, our task is to make democracy safe for the world.
