Gen. H.R. McMaster has written a memoir about his action-packed 13 months serving as national security advisor to the 45th president of the United States. 

It’s titled “At War With Ourselves,” and it focuses on the widening divisions among Americans — divisions not just between the major political parties but very much within them.

H.R. is an historian as well as a soldier, and his mission, in writing this book was, as he spells out for readers, “to explain what the Trump Administration achieved and failed to achieve in the areas of foreign policy and national security during a pivotal moment in American history.”

Gen. McMaster now chairs FDD’s Center on Military and Political Power where Bradley Bowman is the senior director. They both join host Cliff May to discuss the new book and a range of conflicts, crises, and issues.
