It is a problem as old as the new government itself, and they still don’t seem to have a grasp on it. The Libyan National Transitional Council (NTC) is mounting a major Western-backed effort, but they still can’t stop the looting of the former regime’s weapons.
Tens of thousands of missiles were looted, including large numbers of anti-aircraft missiles in the wake of the conquest of Tripoli. And while the NTC were reveling in their victory the weapons depots remained mostly unguarded, allowing massive quantities of the weapons to be ferreted out of the country.
But with the US and other nations throwing major aid at them to tackle the situation, they still don’t seem to have a good handle on what’s going on, and many of the depots remain unsecured.
In the long run, the problem may be “solved” by the caches being totally cleared out. This is less than ideal, particularly for NATO, as Libya had enormous stockpiles of weapons that various militant factions across the region would be eager to acquire.
