What do you think were the 2 most significant events that increased tension during the cold war? and explain.

Alliance system and Brinkmanship.

Explanation: The cold war was a state of tension and mistrust between the United States and the Soviet Union. After World War II, the United States wanted to encourage democracy while the Soviet Union wanted to set up Communist countries.

The alliance system is when countries join forces together to achieve a certain goal. The two alliances that deepened tensions included NATO and the Warsaw Pact. NATO united many western European nations and the United States with the goal of preventing the spread of communism and protect nations attacked by the Soviet Union.

Brinkmanship is the practice of trying to achieve an advantageous outcome by pushing dangerous events to the brink of active conflict such as threatening the use of nuclear weapons. This was a constant possibility during the cold was such as in 1962 when the Soviet Union placed nuclear missiles in Cuba. This escalated tensions between the soviet union and the United States.
