Imagine Iraqis, working for the new government, considering whether to join the police force, or debating whether or not to take up arms. What will they think when they read that the Senate is pressing for steps toward draw-down?

Are they more or less likely to side with a government whose No. 1 partner hints at leaving?

The Senate has responded to the millions who braved bombs and threats to vote, who put their faith and trust in America and their government, by suggesting that our No. 1 priority is to bring our people home.

We have told insurgents that their violence does grind us down, that their horrific acts might be successful. But these are precisely the wrong messages. Our exit strategy in Iraq is not the withdrawal of our troops, it is victory.

Americans may not have been of one mind when it came to the decision to topple Saddam Hussein. But, though some disagreed, I believe that nearly all now wish us to prevail.

Because the stakes there are so high - higher even than those in Vietnam - our friends and our enemies need to hear one message: America is committed to success, and we will win this war.
