Sweden appears to be doing fairly well. Are they fudging the numbers, or listening to science?
I looked at some data from here, but to me it makes things look worse than they actually are because of the logarithmic scale:
Covid-19 in Sweden - charts and statistics
They do appear to be through the worst of it.
One thing that has been common to all countries is that the number of deaths relative to the number of infections drops off with time. I can think of a number of mechanisms that could support this pattern: (1) The more vulnerable people in society get hit earliest and suffer the worst outcomes, (2) As people get sick around them, and other people actually start seeing the real world consequences, those other people start taking protective measures more seriously, (3) People in reality only have contact with a limited number of people and at a certain point, that group of people has either gotten sick or they haven't and won't because they're not in contact with people who are.

Sort countries by deaths-per-million-people by clicking on the column heading.
San Marino is an exception because it is a city-state (total population under 34,000) surrounded by a part of Italy that was hard-hit. I also don't know what their population is like ... if it's biased towards elderly, that could explain the high death rate.
Belgium is something of an exception because early on, they are known to have been over-counting deaths in long-term-care homes, and now it seems that there's no practical way to go back and fix it.
All other countries have been levelling off somewhere between 600 and 700 deaths per million people, including Sweden's lack-of-lockdown situation. Whether this is because there are similarities in how people act and the outcome of the protective measures that have been taken in those particular countries ... isn't known yet.
The USA right now is at 500 deaths per million people and it's increasing at a rate of about 3 to 4 per million people per day. They've probably already got enough cases baked in for the next month ... another 100 deaths per million, bringing it into the same range as several European countries that were hard-hit earlier (Spain, Italy). It will be interesting to see what happens after that. On a country-wide basis, does the death rate naturally level off between 600 - 700 deaths per million people for whatever reason that we don't know? Looks like the USA will be the test for this.
