This special episode of the Explaining History Podcast features historian David Barrett, whose new book 140 Days to Hiroshima examines the decision making regarding the dropping of the first atomic bomb on Hiroshima. This is the first of two interviews with David and it explores the decisions by the Joint Chiefs of Staff and President Truman to use the bomb instead of an amphibious landing in the Japanese home islands.You can purchase the book here: https://www.amazon.co.uk/140-Days-Hiroshima-Un

Explaining History Podcast
For more than a decade, the Explaining History Podcast has helped listeners around the world make sense of modern history. What began in 2012 as a simple experiment—short, accessible episodes explaining major historical events—has grown into a long-running library of carefully researched, thoughtful explorations of the 20th and 21st centuries.
If this was useful, there’s more where it came from.
Every week I publish one piece connecting a current event to its historical roots — free, every Tuesday. Paid subscribers get two additional deeper dives and full archive access.
