Did the Soviets really build a "doomsday machine"? - By Ron Rosenbaum - Slate Magazine
An interesting article well worth reading, which reminds us that while the cold war as such may have ended many of the decisions made during that period may still threaten us.
The possibility that such a Doomsday system may exist is rather disturbing to say the least, and reminds me of far to much disturbing Nuclear war SF that I've read. Especially with the recent reactivation of Russian Nuclear bomber flights.
