The US should use its own primary sources in future to evaluate disease spread. China will lie to the WHO and the WHO will protect it.
But to know the truth, we should use our modern equivalents of Key Hole. There is no truth but that which you have examined yourself.
Thus, we have the WHO. You wanna replace it, it's gonna take a decade to get to another agreement if one even is made. Then it will have its own set of issues. During a pandemic, seems better to me to work with and hold accountable the one we have... kinda like the WH is doing today.
