Which means lots of extra bonus death and instability. There's just no upside here. Saddam's not a target, no matter how cranky Paul Harvey gets. As mentioned, the coalition of 1991 is long gone. Russia and France want Iraqi oil.
Most Arab countries are on the sidelines or opposed to military action.
Even Kuwait is waffling. With the UN extremely unlikely to support a full-scale attack, unilateral action beyond a Tomahawk or three is out of the question. This isn't 1991, with the retreating Iraqi Army trapped on the road to Basra, ready to be carpet-bombed into skulls and cinders. Iraq's Army isn't amassed on a front. It's not even amassed.
