The Cuban Missile Crisis involved the verification of what type of missiles placed 90 miles from Florida?

The Cuban Missile Crisis centered around the discovery of intermediate-range nuclear missiles installed in Cuba, just 90 miles off the coast of Florida. These missiles were capable of reaching a significant portion of the continental United States in a relatively short time frame, which posed a direct threat during the Cold War tensions between the United States and the Soviet Union. The term "intermediate-range" specifically refers to the missiles' range capabilities, which were sufficient to cover distances between 1,000 to 3,400 kilometers, allowing for potential strikes on major U.S. cities. The nuclear aspect is critical, as these missiles were not merely conventional weapons but had the capability to deliver atomic blasts, greatly increasing the stakes of the political confrontation. Thus, the answer correctly identifies both the range and the type of weapon that was central to the crisis.
