> the entire mainstream establishment insisted that imposing them at all was dangerous, counter-productive xenophobia
Closing the borders before patient 1 or almost immediately after patient 1 (plus aggressive contact tracing) would have been good public health policy. Closing the borders after a week of exponential growth and lack of aggressive contact tracing was hopeless. Good for appearances only -- and the good appearances came largely from xenophobia because the public health cat was well out of the bag by that point. See the difference?
I'm sure you can find plenty of bad liberal media takes on the issue, but that's completely beside the point as they were not in charge of anything. The bad (xenophobic) conservative takes didn't just come from the media, though, they also came from the president. Repeatedly and persistently.
> As far as I can tell, the USA had the earliest, most aggressive attempted rollout of testing out of all the countries in the West at least, maybe in the world. There certainly wasn't any lack of enthusiasm for it from the top-level
Just one tiny little problem with that narrative: Trump said the quiet parts out loud, multiple times, confirming what would otherwise have "just" been rumors and leaks. He didn't just fight and stall the testing, he publicly bragged about it later.
"When you do testing to that extent you're going to find more people, you're going to find cases. So I said to my people, 'Slow the testing down, please.' They test and they test. We got tests for people who don't know what's going on."
