I think scholars agree that he wont go down in the pantheon of the greats. (Most svholars are debating as to how close to the bottom his regime was).
However Michael Smerkonish was going over the perceived " high points" of the Trump years and included such things as THE WALL (symbolic action serving no valid purpose), His tax cut (serving one demographic and actually harming others), His bailing from the International Accords (self serving becuse science is busy trying to solve the problem of climate change and Trump has been clueless on this issue), INFRASTRUCTURE, (I cant think of a single project in this area)
Smerkonish then stated that its just too bad Trumps time in office ended with such a deed, and he agreed that Trump is primarily culpable for the travesty in the Capitol (where the entire world saw the savagery of our citizenry).
I believe that Trump' main legacy will be to be recalled as THE LAST ISOLATIONIST (at least I hope its so). This planet is totally integrated ecosystem and needs to be recognized as such.
