NATO helicopter gunships are allegedly aiding the rebels in their fight for Tripoli.
I wonder why the pro-Gaddafi combatants haven't given up already. They're probably too desperate, for some reason or another.
You listen too much to the disinformation seeded by NATO. It has been obvious from the start that journalists have been manipulated (or willingly collaborating?) by western intelligence. Qaddafi had, and apparently still has, some (how much, we still don't know) genuine support within Libya, and this has all along been a palace coup over a background of tribal (personal) loyalties to the players in this coup. The leaders being promoted among these rebels are, by now, all former lieutenants of Qaddafi.
All the stories, repeatedly announced since the very start of the war, that he'd fled Libya were meant to have him do just that (pipe dream!), or to cause the defection of other members of the regime (partly successful). Now the story that the capital had already fallen and he'd been captured/killed/
again fled served the same purpose. If the planners for NATO truly believed that the war was won,
they would not be having presidents and prime-ministers now still calling for Qaddafi's surrender. It's not won yet, they're clearly nervous, which means that this advance on Tripoli may have been a riskier gamble than it seems. I suspect that what you asked here, Winner, actually happened, there are western troops in Tripoli and they can't be kept there much longer unnoticed, despite the lousy quality of what passes for journalism.
