From Iranian help suspected in secret Libyan chemical weapons arsenal
The Obama administration is investigating whether Iran supplied the Libyan government of Moammar Gadhafi with hundreds of special artillery shells for chemical weapons that Libya kept secret for decades, U.S. officials said.
...
The stockpile's existence violates Gadhafi's promises in 2004 to the United States, Britain, and the United Nations to declare and begin destruction of all of Libya's chemical arms, and raises new questions about the ability of the world's most powerful nations to police such pledges in tightly-closed societies.
So was the whole Libyan "revolution" just a way for Al Qaeda to get its hands on all sorts of WMDs that the West didn't know about?
