Check out The Washington Monthly for a great collection on Iraq War and Democracy promotion. I recomend Wesley Clark:
Anyone who has traveled regularly to the Middle East over the years, as I have, knows that the recent hopeful democratic moves in Lebanon, Egypt, and the Palestinian territories have causal roots that long predate our arrival in Iraq, or that are otherwise unconnected to the war. American groups like the National Endowment for Democracy and numerous international organizations have been working with and strengthening reform-minded elements in these countries for years, and to some extent we are now seeing the fruits of that quiet involvement. But it is a mistake to believe that everything that is happening in the region—whether positive or negative—is a result of American military actions or rhetoric from Washington.
In Iran, for instance, the hopeful movement toward democracy went into remission after we invaded neighboring Iraq. Did our invasion cause democratic reform to falter in Iran? Not necessarily. There are many reasons—most of them internal—for why reform movements within a country wax and wane. But it is hard to claim that the Bush administration's invasion of Iraq was responsible for pro-democratic reactions in some Middle Eastern countries, but not for anti-democratic reactions in others.
Conservative commentators are running with the idea that every good event in the world came from the Iraq War. It's a pathetic attempt to try and balance the costs of the War. It's time to take a real honest look at what this war has created.
