This work investigates the legal framework and international norms that governed the United States' decision-making process during the 1962 Cuban missile crisis. Abram Chayes, who served as the Legal Adviser to the Department of State during the Kennedy administration, utilizes his firsthand experience to examine how international law influenced the blockade and subsequent diplomatic negotiations. He argues that legal considerations were not merely peripheral but were central to the strategic choices made by the executive branch to avoid nuclear escalation.
