The Chinese bought the US precious weeks to prepare while it locked down vast numbers of its own population.
The disaster could have been prevented through a vigorous testing/quarrantine program in Washington and California.
At every step of the way the US either bungled testing, or actively discouraged testing. It's been nothing but lies and mistakes from the start.
Like most American catastrophes, this one will only be slowly understood many years after the fact. There will be Congressional investigations and fact finding rituals.
In the end it will come down to three things:
1. Pandemic preparedness was not taken seriously by the incoming administration.
2. Testing was screwed up from the start and never found its footing.
3. The administration actively discouraged testing through both political pressure (e.g. W. Virginia "doing a tremendous job") and rationing of tests.
