Annie Jacobsen's Books Warn of Engineered Pathogen and Nuclear War Risks

Journalist Annie Jacobsen’s recent works highlight two distinct but existential threats. In her discussion of engineered pathogens, Jacobsen argues that rapid advances in gene‑editing tools such as CRISPR allow the synthesis of lethal viruses, lowering the barrier for non‑state actors. She notes that predictive models often overlook human behavior, supply‑chain fragility and digital disinformation, and calls for stronger genomic surveillance and rapid vaccine manufacturing, echoing assessments from the World Health Organization and the Nuclear Threat Initiative.

In "Nuclear War: A Scenario," Jacobsen describes a hypothetical first strike by North Korea against the United States that could cascade into a global nuclear catastrophe. She emphasizes that nuclear conflict is not a series of controlled detonations but a chain reaction of system failures, quoting that it is “a sequence of events that, once initiated, becomes almost impossible to stop.” The book cites more than twelve thousand nuclear warheads worldwide, with the United States and Russia each possessing roughly five thousand, and warns that rising U.S.–Iran tensions could make tactical nuclear strikes on hardened Iranian facilities appear conceivable.
