I agree. This should be an extremely large and extremely serious investigation, no holds-barred.
It could even end up not only as a cause for death penalties, but for a hot war.
One huge problem is that China also knows that they would be the target in a hot war. So, they will do what they're already doing - attempt to destroy all evidence and bar access to the rest.
The other huge problem is that scientists would see such an investigation as, at the very least, risking the end of much viral research for generations. So, it may be hard to find enough good scientists in the field who DGAF about the consequences for their field, despite the fact that one of the best arguments for continued research is a finding that it WAS a weaponization attempt. Far better to make actual bio-secure facilities and develop models and vaccines than get blindsided by something even worse. But anti- hysteria will more likely rule the day.
There may be some solution to these problems, but I haven't got it.
So at this point, we are obviously already in a war against autocracies. As can be seen with RUS supplies of EU natgas, the result of interdependency is coercion, not actual democracy springing up via interchanve. CCP is obviously implementing similar long-term plans on many strategic technologies.
The only way forward today is to literally ban cooperation on this kind of research with such autocracies. CCP has just demonstrated that they will NEVER provide key information in an emergency, no matter how much they 'promised' or 'contracted' to be open.
Yes, international cooperation among peoples can be a wonderful thing.
But we've already done the experiment. If the other people are ruled by an autocracy, it is only poisoning our democracies and building vulnerabilities to future coercion.
