Burning the Green Book - Asmaa Waguih Reuters - full.jpg
Libya has erupted into civil war, with Muammar Qaddafi vowing to fight on to the bitter end, and debate is now growing over whether the U.S. should come to the aid of those fighting to oust him. National Journal, meanwhile, reports that the Pentagon is urging caution and is no rush for the U.S. military to get involved, while the Senate passed a resolution Tuesday calling for a no-fly zone over the country.

Above, opponents of Qaddafi burn copies of "The Green Book"--Qaddafi's 1975 manifesto of government, economics, and social theory--outside the Green Book Studies Center in Benghazi on Wednesday.
