“The acme of skill,” Sun Tzu wrote in The Art of War, is not “to win one hundred victories in one hundred battles,” but “to subdue the enemy without fighting.” The author of Chokepoints: American Power in the Age of Economic Warfare (Portfolio, 2025) has devoted much of his career to exploring how economic power can advance this goal. He served on the teams at the U.S. State Department that designed and negotiated Western sanctions against Russia after its 2014 annexation of Crimea, and whose economic pressure campaign against Iran led to a landmark nuclear deal in 2015. Economic warfare is how America fights its most important geopolitical battles today. From thwarting Iran’s pursuit of nuclear weapons to checking Russian imperialism and China’s bid for world mastery, the United States has reached into its economic arsenal to get the job done. In the process, the world economy has become a battlefield. Its weapons take the form of sanctions, export controls, and investment restrictions. Its commanders are not generals and admirals but lawyers, diplomats, and economists. Its foot soldiers are not brave men and women who volunteer for military service but business executives who seek to maximize profits yet often find they have no option other than to obey Washington’s marching orders. And America’s strength in these battles stems not from its gargantuan defense budget but from its primacy in international finance and technology. This book is about this kind of war. It blends research, analysis, and extensive interviews with more than one hundred of the key players in the events described, highlighting inflection points, interpreting their significance, and pulling back the curtain on the places where economic wars have been fought.
