Let me dumb this down for you: When infections flatten, deaths also flatten in the subsequent couple of months. That's why you saw deaths flatten in the months after their most successful attempt at flattening infections. But as I already showed, infections have more than doubled over the last month compared with their most successful attempt at flattening the infections. That means they are definitely not on the back end of this.
But let's evaluate your other claim, that "deaths have been virtually non-existent for over 3 months. Since you said "over 3 months," let's go with four months. Over the last four months, there have been approximately 85 Covid deaths in Sweden. Pro-rated over a year, that would make about 2550 deaths annually. Not a huge number, right? Well, keep in mind that Sweden has about 1/33 of the U.S. population. So the claim that "deaths have been virtually non-existent for over 3 months" would be akin to the U.S. having over 84K deaths from it. I'll let the entire cities of both Huntington and Charleston, combined, know that if all of them died, it wouldn't be "virtually non-existent."
