I caught the end of Saif Gaddafi's speech on Al Jazeera, and he seems either clueless or flailing. Or maybe he is the sacrificial son, buying time for his father to escape.
He threatened to cut off all oil if the demonstrations do not stop, and that it would take decades to be able to recover a normal society (as if Libya has a normal society) if they do not stop.
It looks strongly like Libya is the next domino. There are reports that riots have hit Tripoli, that some army units have defected to the protesters' side.
The death toll there has passed 200.
