Actually, the majority of deaths in the US have happened since December last year. The nursing-home situation was indeed a big mistake made early on (one of many mistakes made before we, collectively, knew any better), but it is ancient history at this point.
Even in New York State, the recent second wave accounts for about 40% of the total deaths.
