A Plague upon Humanity by Daniel Barenblatt Review: A Haunting, Meticulously Documented Historical Exposé
Daniel Barenblatt's A Plague upon Humanity is a rigorous work of historical research that brings the full, devastating scope of Imperial Japan's biological warfare program — and the postwar cover-up that buried it — into sharp relief, drawing on firsthand accounts from both perpetrators and survivors to chronicle one of the twentieth century's least-prosecuted atrocities.
LuvemBooks Verdict
Best for
Readers with a serious interest in World War II history, war crimes accountability, or the intersection of science and state violence who want an unflinching, evidence-rich English-language account of Unit 731 and the postwar American cover-up that shielded its perpetrators.
Worth it if
You want primary-sourced, morally unflinching history that assigns culpability not only to Imperial Japan's military scientists but also to the American Cold War officials who chose intelligence gains over justice — and you're willing to work through demanding, densely documented prose to get it.
Skip if
You're looking for a fast-moving narrative history; Kirkus's verdict of "surprisingly tortuous" is a fair warning that the book's evidentiary density and multi-front scope — military history, medical ethics, Cold War politics — can exhaust readers expecting a streamlined story.
What readers & critics say
Kirkus Reviews called it "a surprisingly tortuous study" while crediting Barenblatt's decade of reporting with surfacing "hard-won facts" not widely available in prior English-language treatments. Publishers Weekly recognised it as a "useful overview" that provides historical context for the gruesome human experimentation at the program's core.

A Plague upon Humanity by Daniel Barenblatt is a rigorously sourced investigation into Imperial Japan's Unit 731 biological warfare program — its human experimentation, mass-casualty germ warfare operations, and the postwar American cover-up that shielded its architects from prosecution. Drawing on a decade of original research and firsthand accounts from both perpetrators and survivors, Barenblatt builds a damning case that implicates not only the Japanese military but Cold War American decision-makers who chose to absorb Unit 731's data rather than pursue accountability. Best suited to readers with a serious interest in World War II history and war crimes, though Kirkus Reviews' characterization of the study as "surprisingly tortuous" signals that the book's density rewards patient, committed readers over those seeking a streamlined narrative.
- Is it worth reading?
- For readers with a genuine interest in World War II history, war crimes accountability, or the intersection of science and state violence, A Plague upon Humanity offers a depth of primary sourcing — firsthand testimony, newly surfaced evidence — that prior English-language accounts largely lacked. Barenblatt's willingness to assign moral culpability not only to the Japanese military but to American Cold War decision-makers gives the book an unusual and unflinching analytical edge. Kirkus Reviews' note that it is 'surprisingly tortuous' is a candid signal: the book's evidentiary density can be demanding, and readers expecting a fluid narrative may find the accumulated documented detail challenging to absorb. Those with an academic background in Pacific War history or war crimes trials will find the approach well-matched to the gravity of the subject.
- Similar books
- Readers drawn to A Plague upon Humanity are likely to find strong resonance with other works that confront suppressed wartime atrocities and postwar accountability failures. Sheldon H. Harris's Factories of Death is the foundational English-language scholarly treatment of Unit 731. Hal Gold's Unit 731 Testimony provides a survivor-testimony-focused companion. For the broader context of Japanese wartime conduct, Iris Chang's The Rape of Nanking offers a similarly unflinching, rigorously researched account. Readers interested in the Cold War calculus behind postwar impunity may also find parallels in Annie Jacobsen's Operation Paperclip, which chronicles the U.S. government's parallel decision to recruit Nazi scientists rather than prosecute them.
- Who should read this?
- A Plague upon Humanity is aimed at general readers with a serious interest in World War II history, war crimes accountability, and the intersection of science and state violence. It works both as an introduction to Unit 731 for those encountering the subject for the first time in depth and as a contribution to ongoing scholarly debates about postwar justice and American Cold War foreign policy in the Pacific. Readers drawn to works that confront the political dimensions of historical memory — particularly as they relate to decisions made under General Douglas MacArthur's Occupation — will find Barenblatt's argument directly and unflinchingly stated. Those seeking a light or narrative-driven read should be aware of the book's documented density.
- What was the postwar cover-up?
- Barenblatt documents that U.S. Occupation forces under General Douglas MacArthur struck a deal with the doctors of Unit 731 that shielded them from prosecution for their wartime atrocities — a deliberate contrast to the accountability applied at the Nuremberg trials. Pentagon officials chose to absorb Japan's biological warfare data rather than pursue criminal charges, a Cold War calculation that Barenblatt establishes the Allied powers had been positioned to make since at least 1939, when they first acquired knowledge of Unit 731's program. This Cold War calculus forms the moral and political backbone of the book's second half, and Barenblatt is careful to assign culpability not only to the Japanese military but to American decision-makers who engineered the impunity.
- What are the main themes?
- The book's core themes are state-sanctioned atrocity, postwar accountability, and the moral compromises of Cold War geopolitics. Barenblatt interrogates how a sophisticated military-scientific apparatus — Unit 731 — carried out human experimentation and mass biological warfare, while simultaneously examining how that program was deliberately buried by American officials who valued its data over justice. A secondary but significant theme is historical memory: Barenblatt situates Unit 731 within the full arc of Imperial Japan's military aggression, from the staged Mukden Incident of 1931 through wartime Manchuria, arguing that Western historical consciousness has long obscured these events. The firsthand accounts from both perpetrators and survivors give the book an additional human dimension that purely archival treatments tend to lack.
- How does the book portray Shiro Ishii?
- Barenblatt characterizes Lieutenant General Shiro Ishii — the commanding scientist of Unit 731 — in strikingly psychological terms, describing him as 'the archetype of a highly functioning sociopath, playing the dramatic role of the unstable "mad doctor" with flourish.' Rather than treating Ishii as an inexplicable anomaly, Barenblatt situates him within the institutional structures of Imperial Japan's military, showing how the state enabled and empowered his program of human experimentation and biological weapons development. The portrayal is damning but grounded in documented evidence from Barenblatt's decade of research.

Summarize this book
A Plague upon Humanity investigates Imperial Japan's Unit 731, a military biological warfare program active during the 1930s and 1940s, led by Lieutenant General Shiro Ishii. Barenblatt documents atrocities including human experimentation on prisoners, the aerial spraying of cities with plague-carrying fleas, and the deployment of biological weapons against Chinese, Russian, and Mongolian populations — with Chinese researchers estimating as many as 580,000 deaths from Japanese germ warfare operations. The book's second half pivots to the postwar cover-up: U.S. Occupation forces under General Douglas MacArthur struck a deal that immunized Unit 731's doctors from prosecution, a Cold War calculation Barenblatt traces back to Allied awareness of the program as early as 1939. Published by HarperPerennial, it situates Unit 731 within the broader arc of Imperial Japan's military aggression, including the staged Mukden Incident of 1931 that triggered Japan's invasion of Manchuria.

A Plague upon Humanity: The Hidden History of Japan's Biological Warfare Program – Unit 731's Human Experiments and the Post-War Cover-Up by Daniel Barenblatt front cover
What the Book Documents
A Plague upon Humanity investigates the biological warfare program developed by Imperial Japan's military research group known as Unit 731, active during the 1930s and 1940s. At its center is Lieutenant General Shiro Ishii, the unit's commanding scientist, whom Barenblatt — drawing on a decade of research — characterizes as "the archetype of a highly functioning sociopath, playing the dramatic role of the unstable 'mad doctor' with flourish." The program included human experimentation on prisoners, the aerial spraying of entire cities with fleas carrying bubonic plague, and the deployment of dozens of biological weapons against Chinese soldiers and civilians, as well as Russian and Mongolian troops stationed on the Manchurian frontier. Chinese researchers have estimated that as many as 580,000 people were killed by Japanese germ warfare operations, a figure Barenblatt incorporates into his account alongside his own findings.
The Postwar Cover-Up
One of the book's defining arguments concerns not just what Unit 731 did, but what happened — and critically, what did not happen — afterward. Barenblatt documents that U.S. Occupation forces under General Douglas MacArthur struck a deal with the doctors of Unit 731 that shielded them from accountability for their atrocities, allowing key figures to escape the kind of prosecution applied at Nuremberg. He further establishes, through his research, that the Allied powers had knowledge of Unit 731 and its program as early as 1939. This Cold War calculus — in which Pentagon officials chose to absorb Japan's biological warfare data rather than prosecute its architects — forms the moral and political backbone of the book's second half.
Significance and Scholarly Contribution
critics described the work as "a surprisingly tortuous study of Imperial Japan's biological warfare program," acknowledging that while Unit 731 is no longer entirely secret — having figured in news coverage of ongoing Chinese reparations demands — Barenblatt's decade of tracking the story yields "hard-won facts" not widely available in prior English-language treatments. The book's scope extends beyond the laboratory to encompass the staged Mukden Incident of 1931 that triggered Japan's invasion of Manchuria, situating Unit 731 within the full arc of Imperial Japan's military aggression. By incorporating firsthand accounts from both perpetrators and survivors, Barenblatt gives the historical record a human dimension that purely archival accounts can lack.
Strengths and Limitations of the Approach
The book's documented strengths lie in its depth of primary sourcing — firsthand testimony, newly surfaced evidence — and in Barenblatt's willingness to assign moral culpability not only to the Japanese military but to American Cold War decision-makers. Critical coverage review, however, noted the "tortuous" quality of the study, a word that in context signals that the book's density and the complexity of its subject matter can make for demanding reading. Readers seeking a streamlined narrative may find the volume of documented detail challenging to absorb, while those with a prior academic background in the Pacific War or war crimes history will find the evidentiary approach appropriate to the gravity of the subject.
Who This Book Is For
Published by HarperPerennial and now available in a reprint paperback edition, A Plague upon Humanity is aimed at general readers with a serious interest in World War II history, war crimes accountability, and the intersection of science and state violence. It functions as both an introduction to Unit 731 for those unfamiliar with the subject and as a contribution to ongoing historical debates about postwar justice — or the deliberate lack of it. Readers drawn to works that confront the political dimensions of historical memory, particularly as they relate to American foreign policy in the Pacific, will find Barenblatt's argument directly and unflinchingly stated.
