Author Annie Jacobsen raises questions about U.S. readiness for biological warfare in PBS interview

A Pulitzer Prize finalist and New York Times bestselling author is urging closer scrutiny of how prepared the United States is for biological war, in remarks made during a PBS NewsHour interview published August 4, 2026. Annie Jacobsen discussed her latest book, “Biological War: A Scenario,” which frames the threat of weaponized pathogens and how they could cascade into a civilization-ending event.

Jacobsen, who has been associated with research and reporting into difficult-to-verify national security topics, characterized a weaponized biological pathogen as a particularly severe form of potential harm, describing it as “man’s last invention.” Speaking with Geoff Bennett on PBS NewsHour’s “Settle In” podcast, she said the scenario approach in her book is meant to examine what happens when deadly pathogens are intentionally weaponized and how societies respond.

The conversation positioned the key problem not only as the existence of biological threats, but also as the practical readiness of institutions that would be expected to detect, contain, and sustain public health and emergency response. Jacobsen did not describe a specific incident or a confirmed current attack, but instead focused on preparedness gaps and the operational challenges of responding to a deliberate biological event.

PBS NewsHour’s interview format included discussion of what Jacobsen calls a downward spiral: how an engineered or weaponized pathogen could strain healthcare systems, disrupt supply chains, and trigger broader destabilization. The emphasis in the program was on the range of consequences that could follow, rather than on a single set of technical details.

Jacobsen’s book is presented as a hypothetical scenario rather than a documented chronology of a real-world attack. Even so, the interview reflects a broader policy question now entering public debate, namely what capacity governments have to manage a fast-moving public health emergency that is intentionally caused and potentially difficult to attribute quickly.

For public safety and institutional accountability, the interview underscores the importance of planning that extends beyond hospitals and into emergency management, interagency coordination, logistics, and communications with the public. It also highlights the need for readiness efforts that can operate under uncertainty, including when information about a biological agent is incomplete or contested.

The PBS interview serves as an introduction to Jacobsen’s scenario-based treatment of biological warfare and its implications for national and community resilience. Readers who want to evaluate the underlying readiness debate will need to look beyond the framing of a book scenario to the specific preparedness measures, exercises, and policies used by public agencies responsible for health security.
