The Iraq invasion has clearly met its corollary goal of fostering change in the region. As ’05 Lebanese intifada leader Walid Jumblatt put it, “It’s strange for me to say it, but this process of change has started because of the American invasion of Iraq. I was cynical about Iraq. But when I saw the Iraqi people voting [last year], 8 million of them, it was the start of a new Arab world … The Syrian people, the Egyptian people, all say that something is changing. The Berlin Wall has fallen. We can see it.”
