Brookings report warns expanding U.S. nuclear arsenal could raise crisis risk

A report released this week by the Brookings Institution warns that expanding the United States’ nuclear arsenal could raise the probability of nuclear crises. Citing historical case studies and strategic modeling, the study argues that larger stockpiles increase the risk of miscalculation, accidental launch, and escalation during periods of heightened tension. The authors contend that the added complexity of managing a bigger force set may undermine existing command‑and‑control safeguards, thereby making crises more likely rather than preventing them.

The findings arrive as policymakers debate whether to enlarge the U.S. nuclear stockpile in response to China’s ongoing development of nuclear capabilities. By presenting evidence that a larger arsenal could exacerbate rather than mitigate security risks, the Brookings analysis challenges the premise that a quantitative increase is a necessary countermeasure to Beijing’s nuclear modernization. The report calls for a reassessment of strategic options, emphasizing risk reduction and arms‑control measures over sheer expansion of nuclear forces.
