You would prefer a centralized "world government" which could order nationstates around as it wishes ? You dont see that WHO gave all the warnings, and was hoping memberstates - especially the most developed ones - would have surveillance ready, heed the warnings, prepare and react accordingly ?
When the WHO uses wording like "potential", that's never going to get a politician to do anything at all. COVID 19 is a wake up call to humanity that I hope it heeds (but I doubt humanity has the brains to do so). WHO failed, not because of itself, but because no-one listened.
Too many people, too much overcrowding, too much movement.
I want humanity to stabilise and not be obsessed with growth, Growth, GROWTH.
