The changing role of Un forces. Un blog sulla Cnn analizza il ruolo della nuova Un Intervention Force Brigade. Take a look at the video at the soldiers in the Congo. The blue helmets are of course a giveaway – they’re part of the United Nations peacekeeping force. That’s not exactly a terrifying group is it? After all, the U.N.’s peacekeepers have always been seen as a rather hapless, toothless bunch. But this group is different. They are part of the U.N.’s new Intervention Force Brigade. Unlike the rest of the blue helmets, who are only allowed to act in self-defense, as peacekeepers, these soldiers are on the offense, with the authorization to hunt and attack enemy forces. This is a first, a historic change for the U.N., and a new strategy in the Democratic Republic of Congo, where more than five million people have died since 1998 amidst a complex civil war. Over the last 18 months, government troops have been fighting a rebel group called the M-23. The rebels were encroaching deeper into the country, and had already taken over the city of Goma. Meanwhile, the U.N.’s peacekeepers were powerless to intervene – they had no mandate to engage.
