Qadhdhafi's decision in December 2003 to reveal the true scope of Libya's nuclear ambitions and progress resulted primarily from several factors: (1) his increasing desire to regain admission to the international community by renouncing terrorism and weapons of mass destruction (WMD); (2) his fear that Libya might be subject to a U.S. invasion, as had Iraq, on the grounds that it possessed WMD; (3) the interception in October 2003 of a ship bound for Libya with a cargo of Pakistani-designed centrifuge parts manufactured in Malaysia; and (4) the promise that long-standing international sanctions imposed because of Libya's terrorist activities would be lifted, leading to economic and other benefits.
