How did Kennedy apply the Monroe Doctrine to Cuba?

What did the Monroe Doctrine mean to Kennedy in light of world conditions and events in Cuba?

Kennedy defined it as opposition to a foreign power extending its influence into the Western Hemisphere and used that reading to justify efforts to isolate communist Cuba.

Kennedy traced his interpretation to Monroe and John Quincy Adams. He presented events in Cuba as an extension of foreign power into the Western Hemisphere. His answer cited the cutoff of trade and work through the Organization of American States as responses to that development. He also promised continued American effort and attention to Cuba.
