Whether the accusation against the WHO is actually true and not anti-WHO/ anti-United Nations anti-public-health propaganda some parts of it are nothing new, nothing that national health services and agencies are not already doing anyway.
It's already doctors who decide what medications to use in any particular case anyway, and doctors and biologists who advise what vaccines precautions to use in epidemics and pandemics.
Public health agencies already analyse waste water to study pathogen spreads; agricultural safety agencies already impose strict rules on farm animals' health, welfare and transport.
The World Health Organisation is a United Nations body so has no real power over national governments, but the UN works by agreement and can advise on policies such governments can adopt and adapt as they need.
You love to campaign against public health but frankly your latest uncited quote does not frighten me, and probably not many others who would rather live than die needlessly. It is true that bypassing safety tests on new medicines would be bad, even dangerous, and doing so for the Covid pandemic was a desperate but necessary gamble in the face of a highly-infectious animal disease new to our species; but I wonder how exaggerated that lot is.
Glitch has already called your quote "conservative propaganda" but that's probably just American party-politics. I agree it's just propaganda but the world is bigger than the USA's or UK's internal politics and matters of public health should be across political partisanship anyway. Arguing over details is one thing, but the aim and general approach should be co-operative both nationally and internationally.
Much of the world has suffered pandemics from the Mediaeval spreads of Black Death onwards, if not much earlier, and will do so again. New diseases will appear, whilst poliomyelitis, tuberculosis, pneumonia, cholera, Covid-SARS-19 and indeed bubonic plague are still with us and will not go away without a great deal of international effort. Harmful pathogens do not understand national boundaries and cultures, but they do love a good party such as provided by the vast numbers of people mingling in public, and travelling readily around the world every day. None of us want that to stop - though the vast number of purely-luxury holiday flights and ship cruises does raise separate, serious environmental questions - but let's at least know and respect the health hazards, risks and precautions.
Such efforts against these serious diseases are being wilfully obstructed by violence including murder in some developing countries; but are also being wilfully undermined in some developed countries by anonymous propaganda like that you show us, in others.
