Why was a hotline like arrangement felt necessary after the Cuban Missile Crisis?

Correct answer: To reduce misunderstanding and delay during nuclear crisis

The Cuban Missile Crisis of 1962 brought the United States and the Soviet Union close to direct nuclear war. Because both sides were making decisions under great pressure, a delayed or unclear message could have produced a dangerous misunderstanding. After the crisis, leaders saw the value of a faster and more reliable direct communication channel.

Option A is correct because a hotline could reduce delay and help leaders clarify intentions during a nuclear emergency. It was not created to support sea trade, count colonies, or increase industrial production. The hotline did not remove political disagreements, but it lowered the risk that a misunderstanding or slow communication would lead to accidental escalation. This is why it is linked with nuclear diplomacy.
