Well, its already looking like a stalemate and de facto partition. Unless we do something dramatic Misrata will probably fall at some point in the next few weeks. The uprising in the west is unlikely to be re-kindled unless they can see the rebels on the horizon, and that ain't going to happen anytime soon. Of course, we could extend our already slippery definition of "all necessary measures" to include arming and training the rebels inthe east, but then many could justifiably argue that this is going way beyond our mandate, given that any rebel offensive will endanger any civilians who happen to be in the way.
And to think, this time last week this wasn't our problem. Oh, happy days.
