Usually when we debate air strikes on Iran, we're talking about the mullahs' nuclear program. Joe Lieberman talked on Face the Nation today about bombing insurgent training camps. Do we really know where those are? One of the arguments against confronting Iran has always been the fear that the Iranians could step up their meddling in Iraq and make things worse. The case for crippling their quest for nukes seems stronger if it's really possible to curb some of their Iraq operations while we're at it.
