What do they do, exactly? If it's about monitoring and early warnings they seem to have failed pretty drastically.
Not saying i agree with the de-funding, but if they failed as badly as it seems primarily because China told them to stay silent there probably needed to be some kind of reprimand.
If they stayed silent because China told them to then that is a real problem.
In terms of the information they push out and the timing of declaring COVID-19 a pandemic, that is largely dictated by the countries that control it. When it became a pandemic is largely a technicality and is based on an agreed set of rules of when an epidemic becomes a pandemic.
