If you were thinking that nobody is paying close attention to what's going on in Libya, consider this case. Two Americans from Florida were convicted attempting to sell and deliver advanced (and strictly prohibited) military equipment to Libya. This alone demonstrates that the United States law enforcement community is closely monitoring what Libya is seeking to acquire.
The items have military application for use in Special Operations. Whether the US feared that Libya would transfer the technology to Iran, whose IRGC Quds Force would be my best guess for the end user, must be considered. The special relationship with Iran, of certain Libyan factions, is a direct threat to Western interests in the Mediterranean and North Africa.
