with the WHO and our FDA, we'll never know for sure...let's not forget that many viral diseases, including SARS, have been 'Proven' to be the result of a 'Zoonotic' transfer from animals to humans and recent studies show a strong possibility that SARS-CoV-2 (COVID-19) evolved the same way.
To act as if the 'Lab Leak' is THE cause is inappropriate...given the potential for more and potentially more serious virus outbreaks emanating naturally (as before) from China, we need to find ways to ensure China's full cooperation...outright accusations without proof won't help achieve that end.
btw, never forget that Trump slashed our China virus oversight program...'Before' COVID-19...(see link)...that program had been working well for over 30 years and could have given us a better understanding of what was happening...and much sooner...
Here's another point to ponder from this link... ( https://www.politico.com/news/2020/03/25/trump-coronavirus-national-security-council-149285 ) the Trump admin tossed out Obama's NSC pre-pandemic 'Play Book'...would have saved many, many lives...but then, DJT felt strongly that he needed to "Downplay" COVID...even to the extent of calling it a "Hoax"...imagine that.
