The Soviet Union had an absolutely gargantuan stockpile of these missiles, compared to the relatively puny arsenal the Allies had in GWIII. The Allies had at least three, while the Soviet Union had thousands of missiles, thus making a nuclear war suicide for the Allied Nations. However the entire Allied arsenal was destroyed courtesy of Yuri's mind control. Thus forcing the Allies to use the Weather Control Device in their stead. With the death of Albert Einstein before the real World War 3, the Nuclear Missile was not seen anymore but a Vacuum Imploder missile took its place instead.
