Libyan minister Musa Kusa, dubbed "the envoy of death" for his roles in years of assassinations and kidnappings worldwide, has not been included on the United Nations Security Council's sanctions list. 

Kusa, formerly the Libyan head of external intelligence, earned the macabre nickname for plotting assassinations and airline bombings, including the 1988 Lockerbie bombings and the Labelle disco bombings in Germany, which prompted American air raids against Tripoli. 

After Sept. 11, 2001,  Kusa – who graduated from Michigan State University – and the rest of Moammar Gaddafi's regime began cooperating with the CIA to pursue al-Qaeda terrorists. Kusa was the West's main point of contact, and was involved in the negotiations that led to the dismantling of the Libyan nuclear weapons program. 

White House officials described the U.N. list as "dynamic," which means Kusa could be added later on.

“This first block includes those who are most significantly and directly implicated in what has occurred. It doesn't preclude additions to the list depending on what happens going forward,” a State Department official told the Washington Post.

Kusa probably wasn't included because of his ties to the West, anonymous sources told the Post.

Sanctions brought by the United States Monday have frozen at least $30 billion in Libyan assets, an attempt by the Obama administration to prevent Gaddafi from accessing his government and person accounts.

Thirty billion dollars is the highest number the U.S. has ever blocked under sanctions, said David Cohen, the Treasury Department's Acting Under Secretary for Terrorism and Financial Intelligence, to the Wall Street Journal.

Of the 16 on the list, six Libyans have already been removed, presumably because they have since defected.

Despite being left off the list, it's unlikely Kusa will have a future after the Gaddafi regime. Sources say between his ties to the U.S. and his history of assassinations, he "has too much blood on his hands" to be included in any future democratic government. 

"He will not be part of any democratic government in the future, that’s a sure thing,” said Omar Khattaly, spokesman for the Libyan Working Group, to the Washington Post. The LWG has has offices in Atlanta, the United Kingdom, Belgium and the Netherlands.
