> so far no one has proven precisely what factors make the biggest differences.
The problem is in the question itself. Behind it is an expectation that there is just a tiny number of "magic spells" or "a trick" that would "solve" the problem, and that anything else is unnecessary.
The reality is the opposite: all the countries, and where the regulation was weaker, the people on their own, with the time attempted with different levels of success to protect themselves. They all did many things, many real people on many different levels, and with many not identical results. But it's much more complex than the assumption behind the question.
For example, people like to quote Sweden as some "magical other way country" whereas the universities and upper schools were shut down there too, it still has more deaths per capita than the US, the rate of new confirmed cases is not sinking etc.
Also, those who claim that there is an "impact" which "is different" typically don't try to fairly compare the actual impacts which are eventually much more similar when compared properly than implied in such a claim with no correct comparison done.
That is, a lot of such "arguments" are frauds which depend on those hearing it not willing or being able to look at the data properly.
I worked in finance for years, and I can tell you: if those who promote various claims in the news, media and social media would trade while ignoring so much data which is here so obviously available to find and compare, like they do in their claims, they would lose all their money in a blink of an eye.
I don't know how it would be possible to organize that, but if people who claim bullsh.t would have to invest some money behind their claims, and lose it if their claims would be proven wrong, we'd have much less insane conversations.
Just looking at the raw data and comparing can show you that a lot of claims floating around are plainly and completely false.

Additionally, one should search for the original sources of the information for different countries, and compare the numbers based on that additional information.
I can especially recommend translate.google.com for an amazingly efficient way to read some information from the original sources.
