The article proposes a radical rethinking of global health cooperation following the US withdrawal from the WHO, criticizing its evolution into a centralized emergency authority driven by institutional incentives for crisis and distorted funding. It advocates for a "post-WHO" architecture based on functional differentiation. Non-controversial global health functions (e.g., disease classification) should be multilateral and transparent, while emergency powers (e.g., lockdowns) must remain nationally accountable. The authors suggest event-triggered, time-limited compacts among willing states for emergencies, incorporating sunset clauses and post-event reviews. Key reforms include linking funding to objective disease-burden metrics, not institutional growth, and prioritizing investment in national health systems for local resilience. The upcoming 2027 WHO Director-General election is highlighted as an opportunity to push for principles like no permanent centralized emergency authority, transparent budgeting, and preserved domestic implementation, aiming for architectural improvement rather than institutional destruction.
