It's hard to imagine a disaster other than the origin of the coronovirus that the Chinese or USA governments would be more motivated to cover up at all costs. As some have pointed out, if the origin is from a Chinese lab and if the US were directly involved, such as providing virus samples, Chinese cooperation is likely not needed to reach a conclusion.
Fun fact that you won't find on Fauci's wikipedia page other than a vague one sentence mention - that he was hand picked by Dick Cheney and given complete control over US biodefense research.
"...In other words, as far as NIAID was concerned, there was no meaningful administrative distinction between biodefence and scientific research. With the stroke of Cheney’s pen, all United States biodefence efforts, classified or unclassified, were placed under the aegis of Anthony Fauci. So important was this new command structure that a representative from the office of Scooter Libby, Cheney’s powerful chief of staff, was physically placed in NIAID headquarters in Washington during the transition to function as “a kind of political commissar” from the vice president’s office. This gave Fauci unparalleled access to not just Cheney, but President Bush, to whom he had an open channel.
Fauci now had a virtual carte blanche to not merely approve but design and run the kind of research projects he sought — and could do so with no oversight structure above him. Biodefence projects that formerly would have fallen under the authority of military or intelligence agencies were now under his direct supervision."
[Note Ebright mentioned below is convinced covid resulted from a lab leak - maybe his 2003 concerns were prescient or is fitting facts to support his position?]
"...but it was Fauci’s ability to span the divide between science and politics, to “play ball”, that made him essential to the political echelon. The rapid increase in biodefence funding in the post-9/11 world, and the mushrooming of agencies and departments involved in the endeavour, would inevitably draw critics. One was, and still is, Richard Ebright, a major figure in the world of epidemiology who serves as chair of the Board of Governors and is a Professor of Chemistry and Chemical Biology at Rutgers University.
“...This well-intentioned response may perversely have exactly the opposite effect,” Ebright told the Los Angeles Times in 2003, implying that the burgeoning field of biodefence research could lead to leaks, failures, and even a bioweapons arms race. But, by then, the Bush administration had hired a man credible enough to respond to, and, in many ways, outshine the critics. “It’s going to be a challenge,” Fauci told the Times, dismissing Ebright’s concern as “spurious”. “But I have every confidence that the biomedical research community will adapt well to the change.”
"Spurious?"
