The article discusses the implications of the United States' withdrawal from the World Health Organization (WHO), suggesting it offers an opportunity to rethink global health cooperation. It emphasizes that while cooperation is essential due to the interconnected nature of health, how this is structured (architecturally) is crucial. The WHO’s evolution from a normative body to one focused on emergency governance has weakened its original mission and distorted incentives due to a reliance on earmarked funding. The author argues for a fresh approach that prioritizes functional differentiation, distinguishing between multilateral health functions and emergency powers, which must retain national accountability. Instead of a permanent emergency structure, temporary compacts among states triggered by specific epidemiological thresholds could preserve human rights while enabling rapid cooperation. The article advocates for linking funding to measurable health outcomes and strengthening local health systems to build resilience. As the WHO prepares for a leadership transition in 2027, the United States has an opportunity to influence global health governance by promoting transparency, accountability, and clear guidelines to avoid repeating past mistakes. Ultimately, the focus should be on reforming cooperation in a way that emphasizes accountability and reduces reliance on emergency governance without abandoning collaborative efforts.
