I'm curious if you've read any of the discussion around the Pandemic Agreement the WHO's been driving. I've read that several clauses enabled the WHO to unilaterally determine what was a 'medical emergency' and could include such things as automobile safety, firearms safety, and climate, granting the WHO power to create regulations regarding these issues that supersede national policies.
It is political scheming in that vein that makes me allergic to transnational agencies, NGOs, and governments.
