The Power of the Unbuilt Bomb

In Influence Without Arms, Fuhrmann introduces a framework for understanding why states stop short of full nuclearization. By maintaining enrichment and reprocessing facilities, nations achieve a form of "latent deterrence" that allows them to project power through the credible threat of rapid assembly. According to the author, this strategy operates via three primary mechanisms: deterrence by proliferation, where states threaten to build a bomb if cornered; deterrence by delayed attack, which relies on the ability to produce a device mid-conflict; and deterrence by doubt, which keeps adversaries guessing about a nation's true status.

Fuhrmann substantiates his theory with a comprehensive dataset tracking enrichment facilities across thirty-three countries since 1939. His analysis reveals that the decision to remain latent is rarely accidental. While some states view these capabilities as a stepping stone to a full arsenal, others utilize them as a deliberate hedging strategy, a source of national prestige, or an essential pillar of energy security. The quantitative findings are striking: states that exercise restraint with their latent programs experience approximately 35–42 percent fewer interstate crises. Conversely, unrestrained pursuit of fuel-cycle technology often invites the very instability it was intended to prevent, frequently drawing unwanted attention from regional rivals and triggering preemptive strike considerations.

Ultimately, the book challenges the long-held assumption that the nuclear threshold is a binary state. By analyzing cases from Japan to Brazil, Fuhrmann demonstrates that policymakers often view civilian nuclear infrastructure as a functional equivalent to a deployed force. As the global security landscape shifts, this work suggests that the most effective deterrent may not be the bomb itself, but the technical mastery that keeps the world waiting to see if one will ever be built.
