Suitcase Nukes Raise Concern

N E W  Y O R K, Nov. 8 -- Could the next terrifying attack on the nation fit into a suitcase?

The prospect that Osama bin Laden's terrorists may have gotten their hands on small, easily transportable "suitcase nukes" has some people in Washington now truly concerned.

There's no evidence such a device has been smuggled into the country. And even if it had, experts say it would be extremely difficult for terrorists to detonate. And a congressman who has been studying the subject for years on the subject say there's no doubt that such nuclear suitcases do exist.

"I can tell you unequivocally we built these devices similar to this and so did the Soviets during the Cold War," said Rep. Curt Weldon, R-Pa. "The defense minister of Russia told me to my face, 'Yes, congressman, we built these devices. Just as your country built them during the Cold War.'"

In fact, the Department of Defense made a training video in the l960s, demonstrating how "small atomic demolition munitions" can be stuffed into parachutes and attached to Navy commandos, who then show how the weapons can be affixed to bridges and ships underwater.

"These devices were designed to be used to take out major infrastructure facilities," said Weldon. "We destroyed ours. Now the question is, do we know whether or not Russia has them all accounted for and do we know that they destroyed them all?"

Russia Defends Nuclear Inventory

This week in Moscow, Russian President Vladimir Putin told 20/20's Barbara Walters none of the nuclear suitcases is missing.

"I don't really believe this is true," Putin said. "These are just legends. One can probably assume that somebody tried to sell some nuclear secrets. But there is no documentary confirmation of those developments."

But Weldon says he got a much different answer four years ago when he went to talk to with one of Russia's top generals.

The general, formerly Russia's leading defense adviser, said 86 of 132 suitcase bombs were unaccounted for.
