After New Year’s Day 2009, Western media reported that Seif al-Islam el-Qaddafi, a son of the Libyan leader Col. Muammar el-Qaddafi, had paid Mariah Carey $1 million to sing just four songs at a bash on the Caribbean island of St. Barts…

It was Muatassim, too, the cable said, who had demanded $1.2 billion in 2008 from the chairman of Libya’s national oil corporation, reportedly to establish his own militia. That would let him keep up with yet another brother, Khamis, commander of a special-forces group that “effectively serves as a regime protection unit.”

As the Qaddafi clan conducts a bloody struggle to hold onto power in Libya, cables obtained by WikiLeaks offer a vivid account of the lavish spending, rampant nepotism and bitter rivalries that have defined what a 2006 cable called “Qadhafi Incorporated,” using the State Department’s preference from the multiple spellings for Libya’s troubled first family.
