By 1965, the United States and Canada have been at war with the Soviet Union and Chinese People’s Republic for three years. Both sides' atomic weapons are ineffective as surface-to-air missiles shoot down any bombers or guided missiles, so ground forces have done most of the fighting. The Communist nations—whose armies greatly outnumber the North Americans—conquered Western Europe, invaded South America, and are moving toward Texas. All American males are required to either perform agricultural work to feed the armed forces or be drafted into military, construction, or factory service. Food, electricity, and gasoline are rationed, only two CONELRAD stations broadcast on radio, and New York City is reportedly under martial law.
