Why according to Kennedy did the Cuban missiles pose a threat to the US?

According to President John F. Kennedy, the Cuban missiles posed a significant threat to the United States because they brought nuclear weapons within striking distance of American cities and military bases. This proximity increased the risk of a surprise attack, undermining U.S. national security and stability in the Western Hemisphere. The presence of these missiles also intensified Cold War tensions, raising the stakes for a potential military confrontation with the Soviet Union. Kennedy believed that such a situation could lead to catastrophic consequences, necessitating a decisive response.
