They want to know if these are the same disks that disappeared from the lab last month. CNN White House correspondent Kelly Wallace looks at what is on those disks and who might want the information. The two computer hard drives in question, similar to this one, are about the size of a deck of playing cards. Technical experts, showcased here in a 1986 government film who would be dispatched to deal with a nuclear accident, or a terrorist attack involving nuclear weapons. The top secret information on the drives includes details about the United States' nuclear weapons, information about how to disarm those weapons, and intelligence about the nuclear programs of other countries, such as Russia.
Nuclear experts say, suspected terrorists, or so-called rogue states, such as North Korea.
But experts caution that the material on the disks would not help a terrorist or a rogue a mission build a nuclear weapon from scratch. I think it's important to keep in context. I don't think we should treat these disks as the Holy Grail of proliferation. They're not think textbooks for weapons design. In fact, Wolfsthal says the larger concern is that there are still security lapses at the Los Alamos National Laboratory.
