From the LA Times:
Libyan rebels content to wait
An uneasy stalemate settles in eastern Libya as rebel units hold back until troops loyal to Moammar Kadafi run out of supplies or allied airstrikes destroy their weapons advantage.... For now, though, the fighting here has reached an uneasy stalemate, with Kadafi`s forces retaining just enough firepower to beat back sporadic rebel attacks. The ragtag rebel units seem content to wait until the government troops run out of supplies or allied airstrikes destroy their weapons advantage.Thus far, rebel fighters, many of them civilian volunteers, have been unable to exploit the airstrikes that have crippled forces loyal to the Libyan leader. Government forces holed up in Ajdabiya, a city of 120,000, continued to punish the rebels with volleys from tanks and rocket batteries. ...Troops manning government tanks and rocket batteries are now trying to hide from allied warplanes by setting up next to homes and shops, rebels said. But the opposition forces seemed inadequate to the task of driving Kadafi`s men out of the city unless airstrikes first pave the way.
The U.S. has a couple of options to help the Eastern rebels: provide close-air support or declare that they will blast vehicles heading east from Gaddafi`s hometown of Surt toward the oil fields to starve out Gaddafi`s frontline forces. Since the Obama Administration hasn`t yet done either one, I suspect they don`t particularly want the Eastern rebels to win and are instead hoping for a nice quick little coup back in Tripoli so they can declare victory and the Libyans can get back to selling oil.
But who knows? They`re just making it up as they go along, assuming that U.S. air supremacy will let them get away with whatever they come up with. They`re probably right.
