I mean it's certainly no secret that the US government suffered from incredible incompetence when it came to managing the pandemic.
With that said, the start of the pandemic was ~1 year ago. Even if it started right then, 12 months for a country-wide, government-run IT project is a rush job.
This isnt that complex, its an appointment system. with the resources the government had for this they should have been able to produce something workable in 12 months. I find it hard to believe there wasnt something in place they could retool to serve this purpose
Without enumerating the criteria for "right", you're probably not going to get a sensible answer.
A lot of the debate about pandemic management boils down to criticisms of, "did it wrong," without saying what would tip the threshold in the other direction.
This is problematic because it inspires a lot of talking past one another, resentment, and miscommunication. Ultimately it turns into a churn of frustration, defensiveness, and offense.
But even if you manage to get a response to agree on what, "right," means, the depth of their example is likely shallow. (e.g. "Such and such had only 12 infections because they such and such.")
This, too, is problematic, because it presupposes a ton of equivalent variables between the two countries. Population demographics, geographic structure, legal structure, culture, economic stratification, etc.
Conflation between a, "did it right," and a, "did it wrong," country is practically impossible, at least in the context of pandemic response. And anyone who tries to suggest otherwise is either ignorant, lazy, or obtuse.
If you get a satisfactory answer to your query, I'll move to the moon.
That is not the point. America fancies itself as an exceptional country (and it certainly is in certain respects) so it is only fair to expect exceptional results from the American leadership.
