Don’t get too down on Trump because even the Man Upstairs could not see some things in the future. At one point he looked down on his creation and decided he needed to flood the Earth and kill every living thing except for Noah and his gang.
Covid-19 deaths worldwide right now around 25.000 - in a period of 4 months. Number of these elderly people with conditions would have died anyway - so the reel number is actually lower than that.
The world - and biggest part of populations are going to survive this :)
