How does Libya end?
The air campaign against Muammar Qaddafi's forces -- which halted their eastward advance and allowed the rebels to retake coastal towns in eastern Libya -- seems calculated not to go too far. Pro-Qaddafi forces have not, for instance, been heavily hit in the Sitre region in the center of the country, even they are using tanks and artillery against the rebels.
That has stymied the rebels' westward movement and raised questions about whether the ragtag force could take the Libyan capital without a massive bombing campaign.
There is a kind of logic to the idea of a temporary east-west division of the country. The United States and Europe don't want an outright rebel victory to result in score-settling in Tripoli any more than they wanted to watch Qaddafi conduct a massacre in Benghazi. If Qaddafi and his family can be persuaded to go into exile, the way could open for negotiations among Libyan tribes, whose members live in both the east and west.
Too elegant a plan to be carried out by air power? Perhaps. But with President Obama limiting the military campaign and saying Qaddafi is not the target, negotiated settlement would be the only alternative.
