I also agree with you that if this is the outcome we're headed for, then we haven't gotten near any of the big icebergs yet. How's it going to play out and what will the real-world consequences be? I hope that the Biden people will be smart enough to approach this multilaterally and not make it the US vs. China spectacle that you-know-who would have. The fact that they're quietly confirming the facts that have been coming out, but otherwise not yet making a big deal out of it, gives me some hope that they're not idiots.
This is all silly-level speculative and it's possible that nothing will come of it, but I'd place a (small) bet otherwise. The way in which, one by one, the dominos are flipping is truly fascinating. Fauci has flipped, Daszak has flipped. Every few days there's another small but notable change.
I recall a time where evaluation of this was forbidden, with well-coordinated charges of racism. Talking points are a real thing, intense coordination happens intentionally and not among US media. Orthogonal messages, particularly those viewed as adversarial, are suppressed and discouraged. In China government coordination is explicit and acknowledged. The US and UK simply get the same thing through the corporate-government looking glass.
