NATO and The Warsaw Pact

NATO was an alliance made against the Soviet Union. It stands for North Atlantic Treaty Organization. It includes North America and Europe. So if one of their countries was attacked then all of NATO would come and defend that one country. Since the Americas made the NATO alliance, the Soviet Union decided to make the Warsaw Pact. Which included Russia. They were both a mutual defense. These alliances were made so that if one country decided to attack with the nuclear defenses they claimed to have had, they would have backup with other countries who would also jump into the war.
