Six months after Libyan rebels took up arms against the country's leader, Col. Moammar Gadhafi, they have finally toppled him.

But while victorious on the battlefield, they have not been triumphant in political and economic terms. If the rebels are to ensure their revolution's long-term success, they will have to overcome the weaknesses that plague them.

In the days following the start of the uprising in Feb. 17, the rebels formed a political body known as the National Transitional Council (NTC) and a Cabinet known as the Executive Committee. Though drawn from across Libyan society and staffed by people with technical skills, the groups have been hamstrung by several problems.
