Former Defense Secretary Jim Mattis is not talking about President Donald Trump in his new memoir "Call Sign Chaos: Learning to Lead," written with military author Bing West and released Monday.
But the book, styled as a three-part course in leadership tracing Mattis' 40-year career from Marine infantryman to head of U.S. Central Command, still delivers plenty of anecdotes and reflections that will satisfy admirers of the legendary general.
Some may find it too familiar: The book, which is jargon-heavy and prone to repeating phrases such as "doctrine is the last refuge of the unimaginative," riffs on speeches and letters from throughout Mattis' career (the letters are also reprinted in an appendix in the back for comparison) and enthusiastically reprises his greatest one-liners and slogans.
Of his two-year tenure as defense secretary under Trump that ended with his abrupt resignation in December, Mattis says simply, "I did as much as I could for as long as I could." He won't discuss a sitting president, he explains, although certain chapters of the book, such as the one on NATO and alliances, seem especially pointed given his public disagreement with the president on the topic.
