The relationship between President John F. Kennedy and Prime Minister Harold Macmillan was a complex factor in the creation of Anglo-American foreign policies in the early 1960's. Kennedy and Macmillan offers a systematic account of this personal friendship and questions the impact of the relationship, in and of itself, on Cold War policymaking. Assessing the nature of this relationship contributes to a greater understanding of Anglo-American relations, and also provides a tool for understanding the complex nature of international diplomacy during the Cold War. This behind-the-scenes look at the decision-making process reveals the reality of the statecraft and personal diplomacy during the Cold War.
