http://www.nma.tv Libyan rebel forces moved into Tripoli at the weekend, encountering surprisingly little resistance and capturing two of Colonel Gaddafi's sons. There were celebrations all over Tripoli. The green flag of Gaddafi's regime has been replaced with the flag of the Libyan republic. Gaddafi remains in hiding. But his forces are crumbling around him. Many are mercenaries who are unlikely to stick around. Some say he has already to fled Venezuela or South Africa. Others say he'll stay and negotiate with the rebels, who are eager to avoid a bloodbath. Once Gaddafi is gone, all eyes will fall on another dictatorship under pressure - Syria.
