What kinds of conflicts resulted from the global confrontation between the two superpowers

The US and Soviet Union were constantly on the brink of nuclear warfare during the Cold War, resulting in showdowns like the Cuban Missile crisis.

Explanation:

Tensions were extremely high between the US and Soviet Union during the Cuban Missile crisis. In October of 1962, the US found out that the Soviet Union put missiles in Cuba. This directly affected the US, as Cuba is only 90 miles from the United States. These missiles had the capability to destroy nearly every US city.

This resulted in a series of threats and negotations between president John F. Kennedy and the leader of the Soviet Union (Nikkita Khruschev). Ultimately, these men came to a peaceful solution but were mere hours away from all out nuclear warfare.
