In the 1960s, the invasion literature enemy changed from the political threat of Communist infiltration and indoctrination from and conquest by the Soviets, to the 19th-century Yellow Peril of "Red China" (the People's Republic of China) who threaten the economy, the political stability, and the physical integrity of the US, and thus of the Western world. In "Goldfinger" (1964) Communist China provides the villain with a dirty atomic bomb to irradiate and render useless the gold bullion that is the basis of the US economy. In "You Only Live Twice" (1967), the PRC disrupts the geopolitical balance between the US and the Soviets, by the kidnap of their respective spacecraft in outer space, to provoke a nuclear war, which would allow Chinese global supremacy. In "Battle Beneath the Earth" (1967), the PRC attempt to invade the US proper by way of a tunnel beneath the Pacific Ocean.
