Very well-informed and effortlessly funny.

Matthew Sweet’s curiosity and sense of fun pulls back the heavy baize curtains on what we thought we knew about the war.

Operation Chaos is a wild ride—a deeply reported and gracefully written account of a fascinating piece of contemporary Cold War history.

From his book’s opening pages, Matthew Sweet lured me into a looking-glass world of deserters, radicals, spies, and cultists, following them from Vietnam to Sweden to America, with many improbable stops along the way. Operation Chaos tells an American story that had been lost to history, one where people are not always who they seem to be and suspicions have a hard time keeping pace with reality.

Operation Chaos adds a new and fascinating chapter to the story of the Vietnam War. It will amaze anyone who thinks the war was fought only in Vietnam, that it was fought only with guns and bombs, or that it is truly over.

Matthew Sweet’s search for the cult’s survivors is at the heart of this darkly comic story. They are, he finds, still crazy after all these years

In the late 60s paranoia struck deep especially if you were a deserter from the US Army during Vietnam and the CIA was stalking you. Matthew Sweet’s book will suck you into the hall of mirrors in which these guys were forced to live their lives … and still do. Engrossing and accurate. In the Sixties many people were far out but no group went further out than Vietnam deserters to Sweden. Matthew Sweet chronicles their descent into a world of CIA-induced paranoia in the most engrossing style. In telling the story of American deserters from Vietnam, Matthew Sweet captures the moment when the possibilities of the Sixties disintegrated into paranoia. Justifiable paranoia in their case. Excellent.

Sweet evocatively sketches his quest to uncover these resisters’ lives . . . Sweet uncloaks a relatively little-known aspect of the Vietnam War–era counterculture.

A horribly readable account of the US military deserters who found asylum in Sweden during the Vietnam War, and their group’s infiltration by the CIA

It’s the mistrust that interests Mr. Sweet, the book he set out to write morphed into a narrative that goes deep into the hothouse politics of the American Deserters Committee before taking a sharp turn into the bizarre machinations of Lyndon LaRouche. What he does do is tie together a strange story that continues to limp along 50 years after it began.

Operation Chaos offers a new look at the era and the war that forgoes the usual combat and political narratives in favor of something truly strange and bizarre, rife with countless rabbit holes, plot twists and questionable characters and motives. Fortunately, Sweet was willing to throw himself into the middle of the chaos and come back with a confusing, confounding and utterly compelling narrative that spans decades, continents and levels of mental stability.

In this meld of history and reportage, the deserters’ stories, and those of dozens of revolutionaries, hosts, and spies, coalesce into an often moving examination of loyalty and dissent. Sweet details an undercover C.I.A. mission to disrupt defection, and sheds light on the exiles’ complex motives. His quest to track down all the major players in the story takes him, variously, to a maximum-security prison, a cannabis refinery, and Paris cafés.

Can’t recommend Operation Chaos highly enough; a tale of noble intentions sliding into a paranoid mire.

This tale of US military deserters who fled to Sweden during the Vietnam war is as weird and darkly comic a story about Vietnam as you’ll read
