Question

which led to an increase in cold war tensions between the us and the ussr in 1983?
○ a soviet boycott of the olympics in los angeles
○ a breakdown in arms - control negotiations
○ the signing of the inf treaty
○ a new chairman of the communist party in the ussr

Explanation:

• The Soviet boycott of the 1984 LA Olympics was a response to the US 1980 boycott, not 1983.
• The INF Treaty was signed in 1987, reducing tensions, not 1983.
• A new USSR Communist Party chairman in 1983 did not occur; Andropov took power in 1982, and this did not drive 1983 tension spikes.
• In 1983, arms-control negotiations between the US and USSR broke down, directly escalating Cold War tensions.

Answer:

b. a breakdown in arms-control negotiations
