Sino-Soviet split, space race, ICBMs
What event launched the "Space Race"?
Cold War
The period after 1956 was marked by serious setbacks for the Soviet Union, most notably the breakdown of the Sino-Soviet alliance, beginning the Sino-Soviet split. Mao had defended Stalin when Khrushchev attacked him after his death in 1956, and treated the new Soviet leader as a superficial upstart, accusing him of having lost his revolutionary edge. For his part, Khrushchev, disturbed by Mao's glib attitude toward nuclear war, referred to the Chinese leader as a "lunatic on a throne". After this, Khrushchev made many desperate attempts to reconstitute the Sino-Soviet alliance, but Mao considered it useless and denied any proposal. The Chinese-Soviet animosity spilled out in an intra-communist propaganda war. Further on, the Soviets focused on a bitter rivalry with Mao's China for leadership of the global communist movement. On the nuclear weapons front, the United States and the USSR pursued nuclear rearmament and developed long-range weapons with which they could strike the territory of the other. In August 1957, the Soviets successfully launched the world's first intercontinental ballistic missile (ICBM) and in October, launched the first Earth satellite, Sputnik. The launch of Sputnik inaugurated the Space Race. This culminated in the Apollo Moon landings, which astronaut Frank Borman later described as "just a battle in the Cold War."
