From Razib Khan's Living in a World That Is, Not as It Ought to be:
... no matter what establishment voices assert intervention in foreign lands in a ham-handed fashion to prop up our American values is bound to lead us down a path of tears. As Shadi Hamid states the future of democracy in the Middle East is going to be illiberal. This may be inevitable. We don’t need to avert our eyes from it, and we need to acknowledge that so we were, so they will be. It took the Thirty Years war to finally purge the enthusiasm of sectarianism from the cultural DNA of Europeans (and even then, religious minorities were second class citizens for centuries). There will be no calm reasoning with Iraqis of any stripe because the march of history continues, and only sadness can convince all parties that moderation is necessary for the existence of modern nation-states. Intervention in some fashion may be inevitable in the world, but our goal should be to prevent hell, not to create heaven on earth. The former is possible, the latter is not.
