Summary On December 19, 2022, the Diplomacy and Statecraft journal published a book review written by Professor Toshihiko Aono of the Graduate School of Law at Hitotsubashi University. In this article, the professor reviews the book: “The Silent Guns of Two Octobers: Kennedy and Khrushchev Play the Double Game,” written by Mr. Theodore Voorhees Jr. This book examines the mechanisms that prevented nuclear war during the years 1961 to 1962. Most people regard these years as having been closest to a nuclear war, especially during the period leading up to the Cuban Missile Crisis. However, Mr. Voorhees argues against this stating that the year of 1962 was a “surprisingly safe period” and presents a thorough explanation for his argument. Professor Aono praises this book as having contributed to a further understanding of the Cuban Missile Crisis but states that he has some different views from Mr. Voorhees’ arguments.
