A new book by Festival writer Susan Eisenhower comes out on August 11, in which she writes about her grandfather, President Dwight D. Eisenhower.

How Ike Led: The Principles Behind Eisenhower’s Biggest Decisions

Few people have made decisions as momentous as Eisenhower, nor has one person had to make such a varied range of them. From D-Day to Little Rock, from the Korean War to Cold War crises, from the Red Scare to the Missile Gap controversies, Ike was able to give our country eight years of peace and prosperity by relying on a core set of principles

Susan Eisenhower’s How Ike Led shows us not just what a great American did, but why―and what we can learn from him today.

Ike was a strategic, not an operational leader, who relied on a rigorous pursuit of the facts for decision-making. His talent for envisioning a whole, especially in the context of the long game, and his ability to see causes and various consequences, explains his success as Allied Commander and as President. After making a decision, he made himself accountable for it, recognizing that personal responsibility is the bedrock of sound principles.

Susan Eisenhower is a consultant, author and expert on international security, space policy, energy and relations between the Russian Federation and the U.S. A lifelong Republican, she made headlines in 2008 by famously endorsing Barack Obama for president and leaving the Republican Party to become an Independent.
