listen, there's no doubt that trump has made some terrible foreign policy decisions as well, but i'd view pulling out of the who as less concerning than redeploying to the middle east; you gotta take a weighted average, here. biden will do some things i'm ok with, but he's also going to do some things that enrage me.
but, what jumped out at me reading the article was to wonder if a biden presidency might actually be best implemented if it reverses the contemporary roles of presidency and vice presidency. that is, maybe biden is better off letting the vp do the speeches and appearances and stuff, while he tends to legislative priorities. maybe the vp with senatorial experience that he really wants is actually himself.
