Former Soviet spy: Small nuclear devices planted in U.S.
http://www.cnn.com/2000/US/01/28/spy.hearing/ LOS ANGELES (CNN) -- A hooded, former Soviet spy with tales of threats to U.S. security was the star witness at a congressional hearing this week in California. The one-time military intelligence colonel testified that suitcase-sized nuclear devices are hidden on U.S. soil.
"Soviet general staff designed special plan for the future war against America," witness Stanislav Lunev testified Monday in heavily accented English.
It may sound like Cold War-era fiction, but some U.S. congressmen, hoping to convince people the stories are reality, invited Lunev -- who they claim is the highest-ranking defector from Russian military intelligence -- to a field hearing in Los Angeles.
Lunev said his mission was to scout for "dead drop" sites in the United States that were to be used to store communications devices and weapons, including those of mass destruction. "Dead drop" sites were sites at which one agent could leave an item and another agent could pick it up.
"I had very clear instruction: these dead drop positions need to be found for all types of weapons, including nuclear weapons," said Lunev.
Senior U.S. government officials say the FBI can find no evidence supporting Lunev's claims.

In a post 9-11 world, the fact that the FBI can't find no evidence doesn't sound very impressive. They didn't find any evidence that 9-11 was being planned either.

FBI Director Admits Russians May Have Secret Weapons in US
NewsMax.com
http://www.newsmax.com/articles/?a=1999/11/8/73601 FBI Director Louis Freeh admitted that Russia may yet have stored weapons — including nuclear suitcase bombs — at secret locations around the U.S.
The stunning revelations appeared in yesterday’s editions of the New York Post. The paper quoted Congressman Curt Weldon (R-Pa.) as having had a conversation with Freeh in the past two weeks.
Weldon said that Freeh "acknowledged the possibility that hidden weapons caches exist in the United States . . . .”
Weldon, a leading congressional expert on Russia and chairman of the House Armed Services Subcommittee on Military Research and Development, said, "There is no doubt that the Soviets stored material in this country. The question is what and where.”
Congressional scrutiny has focused on dozens of nuclear suitcase bombs that have disappeared from Russian’s nuclear arsenal. According to Russian sources, including Russian General Alexander Lebed, Russia produced 132 nuclear suitcase bombs, each carrying 10 kilotons of explosive material. Only 48 remain in Russia’s inventory; the rest have disappeared.
The FBI has taken a nonchalant approach to locating the secret caches.
