The Long Game, by Derek Chollet

Derek Chollet was a senior director for strategic planning within the National Security Council Staff during the Obama Administration. His book shares, explains, and defends the framework used by key decision-makers in thinking through foreign policy issues during their tenure.

As the title suggests, Chollet identifies as the unifying theme of Obama's foreign policy an unwavering understanding of America's long-term priorities woven into a refusal to be drawn into urgent but ultimately inconsequential distractions.  

The book is largely sympathetic to President Obama. Although not all of the book's arguments are equally persuasive, the insight into the thought process of a nontraditional White House is truly fascinating.
