Purchase options and add-ons
INSTANT NEW YORK TIMES BESTSELLER
Former Secretary of Defense Mark T. Esper reveals the shocking details of his tumultuous tenure while serving in the Trump administration.
From June of 2019 until his firing by President Trump after the November 2020 election, Secretary Mark T. Esper led the Department of Defense through an unprecedented time in history—a period marked by growing threats and conflict abroad, a global pandemic unseen in a century, the greatest domestic unrest in two generations, and a White House seemingly bent on breaking accepted norms and conventions for political advantage. A Sacred Oath is Secretary Esper’s unvarnished and candid memoir of those extraordinary and dangerous times, and includes events and moments never before told.

Review
“A Sacred Oath pulls no punches. It depicts Trump as unfit for office and a threat to democracy, a prisoner of wrath, impulse and appetite. Over 752 pages, Esper’s Memoirs of a Secretary of Defense During Extraordinary Times are surgically precise in their score-settling. This is not just another book to be tossed on the pyre of Trump-alumni revenge porn. It is scary and sobering.” — The Guardian
“Mr. Esper details the all-consuming task of managing America’s largest and most vital cabinet department—instructive reading for those unfamiliar with what operationalizing national security policy decisions involves. Time and again, he shows how presidential inattention, ignorance, incuriosity, duplicity and unwillingness to take responsibility for hard decisions all put the United States at risk…. A Sacred Oath is not a gratuitous tell-all. It is a work of history. Mr. Esper has his perspectives, to which he is entitled, but his willingness to go on the record at length is invaluable. Look forward to the reaction from Mar-a-Lago.” — Wall Street Journal
“A damning portrait of a chaotic, inept administration that posed countless dangers to the nation and the world.” — Kirkus Reviews

- Reviewed in the United States on July 26, 2025Format: HardcoverVerified PurchaseI'm an avid reader of political and military nonfiction books. This is one of the best. Easy to understand because explanations of terminology was included. Author was honest about what went right and what didn't, taking and assigning blame where it belonged without bashjng. Highly recommend.
- Reviewed in the United States on September 3, 2024Format: HardcoverVerified PurchaseReally good book. The author details his time in the military in a way I found both very interesting and very enlightening. I thought I knew quite a lot about the Dept. of Defense. Completely wrong. I knew hardly anything. Loved the author’s descriptions of how DoD works. And, of course, his comments on interacting with Donald Trump were a combination of hysterical and horrifying. Great book by a good man and a patriot.
- Reviewed in the United States on November 24, 2024Format: HardcoverVerified PurchaseThis is a very interesting book and add a perfect time to read it. Gives you insights into what goes on in Washington.
- Reviewed in the United States on February 23, 2023Format: HardcoverVerified PurchaseIf you prefer light subjects don't read this. If you want to take the time to really expand your knowledge of world affairs and the role of The United States in them, this is well worth your time. It's also a huge indictment of Donald Trump from someone who was there: Esper was Trump's Secretary of Defense for the last 18 months of the Trump administration. Example: Trump was not joking when he suggested that we bomb drug labs in Mexico. Esper was in shock at the suggestion because: A. Any bombing would be considered an act of war upon a country which is our ally. B. It inevitably would kill innocent civilians. Just one of the MANY examples of when Esper had to use his own ethics and common sense to guide Trump away from a horrible decision that would have had huge negative consequences.
- Reviewed in the United States on October 12, 2022Format: HardcoverVerified PurchaseI never knew much about Secr. of Defense Esper while he was in the role. I got the book hoping to get an inside look at the Trump administration from a DOD perspective. The book provides some of that so it is not a total waste. However, a lot of the book is basically a self justification for what he did and why he stayed in the job. That kind of apologist writing is much better when done by someone else on your behalf. While it may be an honest explanation when done by the person himself, it does not come off well. Unless you are really curious about Esper personally, you can pass on this book as offering any major insights on Trump and his actions. (I would contrast this with Deborah Birx's book where she honestly owns the things she did wrong and her personal failingsi n her Covid role. It is more genuine than Esper's attempt at reputation preservation.)
- Reviewed in the United States on May 20, 2022Format: KindleVerified PurchaseSecretary Esper was a class mate of mine at West Point. I have always admired the principled leadership he brought to his service to our nation. It stands in stark contrast to that he describes of the administration for whom he served in as Secretary of Defense. What struck me as most admirable was how Mark was able to bring meaningful improvements to the the office in the short time he was there despite almost constant major distractions and fire fights abroad and at home. His description of the budgeting process he brought to our nations biggest line item of spending is an especially valuable lesson other areas of government should adopt. I hope it and the other improvements he initiated continue as a model going forward past his dismissal. We can all learn leadership lessons from the stories he describes and we are lucky to have had him in office for as long as he remained there.
- Reviewed in the United States on September 4, 2022Format: HardcoverVerified PurchaseUnlike Bill Barr's self-serving, name-calling "book", which ended up in my trash, this book gives real insight on what it was like to be on the "Trump team." I am a middle-of-the-road Democrat (yes, there are a lot of us) and have nothing but praise for Esper and his allegiance to his sacred oath to the Consitution and not to a man. There is a lot of his views that didn't go down well with me, but all-in-all, when we needed a real patriot in important positions, Esper lived up to the test. The book is well-written, but rather long. And, he really needed to tone down the patting himself on the back somewhat. The book deserves its place on the shelf of American history.

conjunctionReviewed in the United Kingdom on May 22, 20225.0 out of 5 stars For this Limey, Well Worth the Effort
Format: KindleVerified PurchaseI am 72 years old, British, and I don’t think I have ever voted Tory in my life. I have nearly always voted Labour. So you might think why am I reading the memoirs of Mark Esper, a loyal Republican who for 18 months up until being fired by Trump just after his election defeat was Secretary of Defense, ie the guy in charge of the Pentagon, in charge of the entire US military.
I read it because a review I read in the Guardian suggested it offered a better perspective on Trump than other books exposing the goings on in the White House because of Esper’s integrity and how his commitment to the apolitical nature of his post, running the military meant that his loyalty was to the American Constitution and not necessarily the President.
In fact most of this book is not really about Trump at all but about what he considers he achieved in terms of maintaining and reordering the US military, and his reasons for his actions. Also like one or two other books about US politics and history I have read over the years it offers a very clear understanding of the structure of US government especially the relations with the Chairman of the Chief of (military) Staffs, with the State Department, the National Security Council and so on. However compared to other books I have read you feel Esper is writing for an American audience who would naturally already have a basic understanding of these things, he doesn’t spell it all out.
Of course as an English person there are a lot of things I don’t understand about contemporary US politics, especially the breakdown of bipartisan politics and Esper doesn’t go into the political scene in general. This is strictly a personal memoir about the role of the Department of Defense, and his role as Secretary, and his relationship with Trump and Trump’s henchmen especially Robert O’Brien and Mark Meadows. Interestingly Mike Pompeo and especially Bill Barr come out pretty well here. And Bolton too.
The book offers a very clear picture of how Trump would often be reasonable and charming and without warning lurch into red-faced anger in which he would ignore a series of policies he had recently agreed with, and that had been worked out laboriously in conjunction with several US Departments of government. At other times he could be thoughtful and constructive, but sometimes it seemed to be all about his own position, especially as the election approached. And as we know, he hasn’t gone away yet.
The most important areas of conflict between Esper and Trump were around Trump abrogating proper procedure and trying to get decisions made about committing the US military to a variety of actions at home and abroad without any proper planning or consideration of the consequences. Esper worked very hard with certain colleagues to gently get Trump to consider other options and this in itself was a fulltime job. The biggest issues in terms of difficulty were the responses to the disturbances over the murder of George Floyd and the increasing craziness in the White House in the run up and the immediate aftermath of the 2020 election. Esper was fired by Trump a few days after the election. Esper restricts his comments to the period he was Secretary for Defense, (and before that Secretary of the Army), so he doesn't comment on the storming of the Capitol, he restricts his comments of that of which he knows.
The book is not difficult to read except in that there is a lot of detail about all the matters he had to consider so for a Limey it takes some concentration, but for this Limey it was well worth the effort.
Amazon CustomerReviewed in Canada on June 14, 20225.0 out of 5 stars The work behind the position!!
i was fascinated with this book. I am so in awe of what a Secretary of Defense must know and execute daily. What a job!! Made all the more difficult with Trump as the President. This theme is not , however, the overriding story in the book. It tells the reader how precarious government and democracy is in this day and age and if the right people are not in the right positions how the world could be in trouble. An excellent read.
