This is Kaplan’s first collection of essays since his classic The Coming Anarchy was published in 2000. Drawing on decades of firsthand experience as a foreign correspondent and military embed for The Atlantic, as well as encounters with preeminent realist thinkers, Kaplan outlines the timeless principles that should shape America’s role in a turbulent world: a respect for the limits of Western-style democracy; a delineation between American interests and American values; an awareness of the psychological toll of warfare; a projection of power via a strong navy; and more.

From Kaplan’s immediate thoughts on President Trump (“On Foreign Policy, Donald Trump Is No Realist,” 2016) to a frank examination of what will happen in the event of war with North Korea (“When North Korea Falls,” 2006), The Return of Marco Polo’s World is a vigorous and honest reckoning with the difficult choices the United States will face in the years ahead.
