I suspect my own country, Australia, will happily go along with the proposed treaty. In the UK at least, there is the beginnings of a debate. Here Mr Danny Kruger makes the case for “subsidiarity” decisions made as close as possible to the people affected. “Power to the people!”
I give this post the tag “the road to hell…” as I’m sure people pushing this WHO Treaty idea have (largely) good intentions. But outcomes may be worse. I do not see anything that happened during Covid that was better because global efforts. As Kruger notes, even vaccines were developed quickly only because of competition between countries and companies.
