"The Surge Has Worked."

As slogans go, it lacks the sizzle of "Shock and Awe" or "Mission Accomplished." But it's not bad.

Isn't it interesting, though, to watch John McCain and the Republicans manipulate the message? Now, to have commander-in-chief or even Congressional credentials, one must have been prescient enough to have supported the surge from the start.

No need to rehash that tired old argument about us invading a country in search of weapons of mass destruction that turned out not to exist. No reason to discuss the failure to anticipate the insurgencies and sectarian violence that led to the death of thousands of U.S. troops and many more Iraqi citizens after President Bush's "Mission Accomplished" moment.

Now it's all about the surge. If you supported it, congratulations. You are presidential material. If you didn't, you might as well pack up and go home. Clearly you don't have what it takes.

I really hope that, at some point in this campaign season, we get an honest discussion by the candidates about the events and mistakes that led to the debacle that is the Iraq war, and how we can avoid falling into a trap like it in the future.
