to decrease the tension during the cold war
The superpowers controlled the world. If lesser nations disrupted world peace, the superpowers intervened.
M.A.D- mutually assured destruction. Since both Superpowers (USSR and USA) had a nuclear weapon, they knew that if one will attack the other, both atomic bombs would have been fired and they would have destroyed the world. Therefore, they fought in Arm race, Space race and Proxy wars (wars fought by smaller countries on the behalf of the superpowers). Also, in the Cold war there were no actual fighting between the USSR and the USA. Hope it helped :)
It was a 'race' between the two superpowers during the cold war era, USA and the USSR. Both countries can claim different victories, USSR sending the first man into space, who made one complete orbit of the earth. The USA were the first to land a man on the moon in June 1969.
