What has been the longest-lasting aspect of tensions that arose between US and Cuba in 1960s?

The Cuban Missile Crisis was a 13-day confrontation in October 1962 between the United States and the Soviet Union over Soviet ballistic missile deployment in Cuba. It is considered one of the most dangerous moments in human history, as it brought the world to the brink of nuclear war.

Although the immediate crisis was resolved through diplomacy, the long-term consequences of the Cuban Missile Crisis continue to shape US-Cuba relations today. The United States imposed a trade embargo on Cuba in 1962, which remains in place and is the longest-running economic embargo in history. The embargo has had a devastating impact on the Cuban economy, and has been a major source of tension between the two countries.

In addition to the trade embargo, the United States has also maintained a policy of isolation toward Cuba, refusing to recognize the Cuban government and opposing its membership in international organizations. This policy has further strained US-Cuba relations, and has made it difficult for the two countries to cooperate on issues of mutual interest, such as drug trafficking and environmental protection.

The long-lasting tensions between the US and Cuba are a reminder of the complex and often hostile history between the two countries. The Cuban Missile Crisis was just one episode in this history, but it had a profound impact on US-Cuba relations that continues to be felt today.
