Iran is conducting a proxy war against the United States in Iraq, declared Ambassador Ryan Crocker last week.

How? Gen. David Petraeus explained. The Quds Force of the Iranian Revolutionary Guard and Hezbollah are arming, training and directing the Shia militia fighting U.S. and Iraqi forces in Basra and firing rockets into the Green Zone. Said Petraeus, the Quds Force is responsible for killing hundreds of American soldiers.

If true, these are acts of war from a privileged sanctuary. And Bush would be as justified in attacking these Iranian base camps as was Nixon in ordering U.S. forces to clean out the North Vietnamese sanctuaries in Cambodia.
