Route 1 US founded WHO (1948), principal funder + agenda-driver (surveillance, PEPFAR) → exit raises existential questions for global health governance

Route 2 withdrawal as latest US unilateralism (like Paris exit) → deepens democratic deficit in global governance

immediate impacts (funding gaps, reduced US influence, widening health inequities, weakened pandemic coordination, eroded trust) → domino/legitimacy risk (populist/nationalist agendas superseding multilateralism; US loses surveillance + early-warning access) → these expose Stiglitz’s accountability deficit (opaque, unaccountable institutions) → reimagining begins → diversify + stabilise financing (no single donor) → transparency + streamlined decisions + Independent Panel recommendations → greater voice for emerging economies + non-state actors (representation)

nationalist–unilateralist retreat (sovereignty over multilateral commitments) vs. interdependence (borderless threats, shared vulnerability, no one safe until all safe)

Route 1 no population secure until all protected → Linklater’s post-national community of shared problems → multilateral solidarity as safeguard

Route 2 crisis as opportunity → reimagine a more representative, better-financed, more effective WHO
