That wasn't the point of the video, though. The US media all claimed the lab leak was debunked right from the start, they called it a conspiracy theory. Lab accidents happen all the time!
To be fair, there was no evidence there was a lab leak. Only conjecture. On the balance of probabilities, nature, the wet markets, high population cluster and frequent animal encounters with species such as bats etc, was always greater than the probability of a lab leak
I'm pretty sure behind the scenes politicians they also considered a lab leak - but what they say in public has to be tamed
It would do no good to whip up an already xenophobic populous into a frenzy against Chinese. They wanted / needed China on side to get to the bottom of this. Pointing the finger at China so early on when you dont have any evidence except to say 'well it could have been' is just not good enough. So the 'over confidence' on display about it coming from nature or the wet markets etc was probably for that. You dont expect a politician to show all the cards and be straight up with the public and their foreign 'rivals' (China) do you?
But China has burnt all its good will and all its relationships anyway and as we gather more evidence (or absence of evidence on previous ideas such as wet market origin and finding no corona virus samples), then we can narrow down the origin to the lab with confidence
I dont think anyone with a brain believes China would deliberately unleash an unknown and novel virus on the world starting with its own population. If they really wanted to do something like that, they would just take it to another country. But again, why would they because the outcome of a trashed world economy is going to hit China pretty hard too given they do business with the world
One conspiracy theory that can be debunked for all time is that this virus was man made. If it were, scientists the world over could spot the telltale signs it has no natural origin. There is universal agreement of any scientist worth their salt it's of a natural origin
Of course, videos like these are funny to mix. Hindsight is a wonderful thing and everything ever said these days is forever. You've even got a clip of our PM in there. Ugh! I notice the video was very selective in what it clipped.... Our government back in April 2020 called for an 'independent investigation into the origins' (you dont see that in your video) and thus China cracked the shits (and the fact they got so angry at the idea of an independent investigation kind of hints they had something to hide)
