In a context of existential transnational challenges and growing inter-state rivalries, we need well-financed, universal multilateralism that can set global rules and norms, drive forward action, and sidestep the tendency for money and military might to buy global influence. The WHO Executive Board now has an opportunity not only to reinvigorate its own organisation, but also to advance a discussion on how the entire UN system can be placed on a stronger, more financially sustainable footing. Passing up this moment out of fear of the implications for member state fiscal obligations to the wider UN system would be both unfortunate and short-sighted.
