The mission of the coalition of nations to protect Libyan citizens by "any means necessary" is now four weeks old, but the strength of the mission is becoming increasingly tenuous. Britain and France are now spearheading the intervention since the United States handed leadership off on March 31, but the NATO coalition seems increasingly splintered as it struggles with a mission that expressely prohibits the toppling of embattled Libyan leader Muammar al-Qaddafi. Meanwhile, Qaddafi's forces are besieging the city of Misurata, and have adopted tactics that make them less of a target to Western air power.
