> This is a false equivalency. China is a totalitarian state that quite literally controls information; Japan and the US are not in any real sense.
This is true, but what makes both the US and China (and many other countries at the moment) similar is they are controlled by governments with strong nationalist tendencies. Any state has the ability to control these stats by limiting the availability of testing. A nationalist-leaning state has an even stronger incentive to do so, because it leans even more heavily on the thesis that its nation is essentially different than others. This however, runs into the reality that this virus doesn't differentiate based on our cultural construct of nations.
Until a few days ago, you saw this most markedly in India, which just recently made a sudden U-turn in its denial of the problem.
In China's case, nationalism is coordinated with its totalitarianism, which as you point out makes it different. The Chinese response should be scrutinized for its initial failures as much as its later successes.
The saving grace in the US is that even though we have leadership incentivized by nationalist and self-preservatory urges to minimize the true magnitude of the problem, hospitals and state/local officials can publicly express that they are seeing a large number of likely cases that they can't test for, and publicly demand more testing and treatment capacity from federal authorities.
That is pretty much the dynamic that has been happening in the US for nearly a month - exemplified in the public war of words between state governors in initially affected states (CA, NY, MI, etc) and the Administration. And at this point, it's abundantly clear that the tide of truth is on the side of those state governors and public health officials. This is why military hospital ships are now showing up in Los Angeles and New York.
