For me "countries that did really well" is mainly places like Singapore and Taiwan and South Korea, which got the virus earlier than USA and Europe but took it seriously from the very start.
However... at least for Taiwan that doesn't feel like it adds up:

They've had fewer than 1700 cases, and that's including a recent massive outbreak. They peaked on March 26th 7-day average with 21 cases a day. Granted, the US took maybe a couple more weeks to ramp up to its first plateau, so maybe if it was caught here a few weeks earlier it would have made all the difference. But it feels a lot more like Taiwan just didn't have a lot of travel to and from Wuhan?
The current Vice President of Taiwan, Lai Ching-te, has a Master's degree in Public Health from Harvard. The previous VP, Chen Chien-jen, has a Master's degree in Public Health from National Taiwan University. Taiwan takes public health seriously, especially after the original SARS experience.
Nobody in Taiwan thinks the virus is a "scam" or that masks are a "tool of oppression." Even before the pandemic masks were totally common. There is complete public buy-in on masks without even having to be asked. Some of my friends work in a clinic in Taipei so I hear updates. I was also in Taiwan last year for a month. The difference in attitude between the US and Taiwan is startling. If the US had acted like Taiwan, instead of acting in a way that was indistinguishable from sabotage, we'd have a lot fewer deaths and would have avoided a recession.
That’s bad, it might get a lot worse, and we’re all nervous — but just wanted to add the context because “massive” can mean a lot of things with orders of magnitude difference.
BTW is there a vaccination drive over there? That's got to calm things down somewhat right?
There are all kinds of effective measures (e.g. contact tracing, quarantining of unconfirmed suspect cases) that work when you have 20 cases a day and don't work when you have 2000 cases a day, so going all-in while you still have just a few cases works, because by the time you have many cases, it's too late.
