This strains credulity. 45M excess deaths over 3 years -> 15M/year. Before 2020, the U.S. had never had more than 3M deaths. According to this graph, the number jumped up by a about a half a million death in 2020 and then by another 100K in 2021, before dropping back about 200K in 2022.
That's still about 1.5M excess deaths over the course of the "pandemic" -- and the deaths continued high even after "COVID" became a negligible factor.
The funeral business could not have kept secret an additional 40M deaths.
