Thinking his work is done, the Palestinians kill Fromm. However, Fromm had not yet told them that some of the material he planned to use needed to be purified first. The Palestinians finish the bomb assembly and when it is used, the impure material causes the weapon to fizzle. However, almost everyone at the Super Bowl is killed, including the Secretary of Defense, the Secretary of State, and the commander of NORAD. With the corresponding attacks in Berlin, the United States briefly assumes DEFCON-1 status as Fowler and Elliott prepare for a nuclear war. The crisis is averted by Ryan, who learns of the domestic origin for the bomb's plutonium, gains access to the hot line, and convinces the Soviet President to stand down his country's military.
