the DEFCON level toward a retaliation that will start World War III. David learns the true nature of his actions from a news broadcast, and FBI special agents arrest him and take him to NORAD. He realizes that WOPR is behind the NORAD alerts, but he fails to convince McKittrick (who believes David is working for the Soviets) and is charged with espionage. David escapes NORAD by joining a tourist group and, with Jennifer's help, travels to the Oregon island where Falken lives under the alias "Robert Hume". David and Jennifer find that Falken has become despondent, believing that nuclear war is inevitable and as futile as a game of tic-tac-toe between two experienced players. The teenagers convince Falken that he should return to NORAD to stop WOPR. WOPR stages a massive Soviet first strike with hundreds of missiles, submarines, and bombers. Believing the attack to be genuine, NORAD prepares to retaliate. Falken, David, and Jennifer convince military officials to cancel the second strike and ride out the attack. When the targeted American bases report back unharmed, NORAD prepares to cancel the retaliatory second strike. WOPR tries to launch the missiles itself using a brute-force attack to obtain the launch codes. Without humans in the control centers as a safeguard using the two-man rule, the computer will trigger a mass launch. All attempts to log in and order WOPR to cancel the countdown fail. Disconnecting the computer is discussed and dismissed, as a failsafe will launch all weapons if the computer is disabled, acting like a fail-deadly ignition to World War III. Falken and David direct the computer to play tic-tac-toe against itself. This results in a long string of draws, forcing the computer to learn the concept of futility and no-win scenarios. WOPR obtains the launch codes, but before launching, it cycles through all the nuclear war scenarios it has devised, finding that they all result in draws as well. Having discovered the concept of mutual assured destruction ("WINNER: NONE"), the computer tells Falken it has concluded that nuclear war is "a strange game" in which "the only winning move is not to play." WOPR relinquishes control of NORAD and the missiles and offers to play "a nice game of chess". Cast Production Development Development on WarGames began in 1979, when writers Walter F. Parkes and Lawrence Lasker developed an idea for a script called The Genius, about "a
