Answer: False
Explanation:
The cold war was a decades long conflict between the United States (and it's allies) and the former Soviet Union (and it's allies).
Near the end World War II the United States developed the atomic bomb, several years later the Soviet Union had developed atomic weapons as well. The destruction caused by this new type of weapon created fear of open warfare between the United States and the USSR across the entire world.
This forced the "super powers" of the United States and the Soviet Union to fight "proxy wars" using other nations (such as Afghanistan, Cuba, etc.) because direct warfare between the "super powers" would likely lead to destruction of the human civilization (because of the atomic weaponry).
The cold war also caused the arms race -- rapid development of weapons and defense technology by the US and USSR. The arms race, in turn, caused the space race (space shuttles, rockets, space exploration, etc) because the technology developed to travel to space could be easily modified to create missiles that could travel from one continent to another. These inter-contintinental ballastic missiles carried nuclear weapons on board.
This is a huge simplifying of the cold war but hope it helps.
