About a week before Jeff Sharlet’s new book , The Undertow: Scenes from a Slow Civil War, was published in March, a new video was uploaded on YouTube. It was a short documentary from 1983 of when Harry Belafonte, an iconic American singer and actor, visited East Germany to perform in a concert promoting communism . The “World Peace Concert” was run by East Germany’s communist youth organization. Belafonte gave his blessings to the Soviet-sponsored campaign promoting unilateral Western disarmament.

The Belafonte concert is barely mentioned in The Undertow, a collection of essays and reporting by Sharlet, an award-winning journalist who teaches at Dartmouth College. Indeed, little of the Left’s history of flirting with authoritarianism is mentioned at all. Instead, The Undertow argues that a bunch of crazy right-wingers, including militia groups, are bent on conflict with the Left. They want a second civil war, Sharlet claims, and those who stand up to oppose them are American leftists, portrayed as Christlike figures of light and wisdom.
