Why did Kennedy not call his action a blockade?

President Kennedy refrained from calling his action a "blockade" during the Cuban Missile Crisis because the term carries a connotation of war and implies a more aggressive military stance. Instead, he referred to it as a "quarantine," which suggested a defensive measure aimed at preventing further military supplies from reaching Cuba without formally declaring war. This choice of language allowed him to maintain diplomatic avenues and reduce the risk of escalating tensions with the Soviet Union. By using "quarantine," Kennedy sought to emphasize the intent to protect U.S. security while avoiding a direct confrontation.
