I do not make this decision lightly. I opposed the war in Iraq precisely because I believe that we must exercise restraint in the use of military force, and always consider the long-term consequences of our actions. We have been at war now for eight years, at enormous cost in lives and resources. Years of debate over Iraq and terrorism have left our unity on national security issues in tatters, and created a highly polarized and partisan backdrop for this effort. And having just experienced the worst economic crisis since the Great Depression, the American people are understandably focused on rebuilding our economy and putting people to work here at home.
