Mattis is scathing about a former president in Call Sign Chaos: Learning to Lead, which is released today, and he doesn’t hesitate to name him: Barack Obama.
The former general's opinion of Obama, for whom Mattis was head of U.S. Central Command from 2010 until 2013, might be summed up by a single entry in the book’s index: “Obama, Barack, strategic thinking lacking.”
Mattis summarizes his time commanding CENTCOM, overseeing military operations in the Middle East and Central Asia until Obama fired him, in harsh terms: “It was to be a time when I would witness duty and deceit, courage and cowardice, and, ultimately, strategic frustration.”
He details in the book how Obama and Vice President Joe Biden, who was in charge of Iraq policy, were “ignoring reality”.
Obama made “catastrophic decisions” in Iraq, Mattis concludes. And he did so because he ignored the advice coming from multiple military and civilian advisers, thinking he knew better than all of them.
“It’s frustrating to listen to any leader blame his predecessor, especially a political leader regarding a situation that he knew existed when he ran for office,” Mattis says, referring to Obama's disdain for Bush.
He has one last parting shot for his old boss Obama: “Acting strategically requires that political leaders make clear what they will stand for and what they will not stand for."
