Abstract: A system for controlling the nuclear arsenals of two adversaries. The system includes a central control computer that is in communication with at least two command terminals, each operated by one of the adversaries. The central control computer is in communication with the missiles and has exclusive control over the launch sequences needed to fire them. To fire a missile, an adversary must make a request to the central control computer from a command terminal. When a first strike is requested by one adversary, the central control computer allows the other adversary to fire their missiles while preventing the requester from firing for a predetermined amount of time. The system includes computers on-board the missiles that allow the central control computer to monitor whether any missile is being tampered with. The system further allows the adversaries to request permission for the decommission of any missiles.
