Some excellent perspective on the war in Iraq from Fouad Ajami in the Wall Street Journal:
It is not easy to tell people of threats and dangers they have been spared. The war put on notice regimes and conspirators who had harbored dark thoughts about America and who, in the course of the 1990s, were led to believe that terrible deeds against America would go unpunished. A different lesson was taught in Iraq. Nowadays, the burden of the war, in blood and treasure, is easy to see, while the gains, subtle and real, are harder to demonstrate. Last month, American casualties in Iraq were at their lowest since 2003. The Sunnis also have broken with al Qaeda, and the Shiite-led government has taken the war to the Mahdi Army
