I think this is all a different issue. Wanting to know what happened is fine. Sanctions are fine if we're talking about a continuing issue. Trying to negotiate a settlement is fine. The idea that we should impose "punishment" on other countries as a response amid a crisis that was largely a result of an incompetent response to a problem by our own gov't is reflective of a mindset that is both authoritarian and childish.
There's also something really creepy about the way people are so easily manipulated as Trump's relationship to China keeps changing (immediately gives in to them on the TPP and it's great that we're building a stronger relationship, then pivots to a trade war and they're the devil, then pivots to playing nice to get out of the trade war and they're great, then needs a scapegoat for his failure on COVID, etc.--every step of the way, his slavish followers shift and express the new gov't-demanded position with deep conviction).
