I didn't see any of it, so perhaps I am being unfair. But I suspect the narrative is supposed to be "Truman started it -- you know, that SOB dropped nukes on Japan!!" then we skip right over JFK and almost all of LBJ -- and WHAM! "Here we have Richard Nixon burning down villages to save them and personally ordering the Mai Lai massacre, and napalming little children -- darn that Nixon! He was a Republican you know. Very much like Donald Trump ..."
You're right. You're being unfair. The rest of your post bears no resemblance to the episode aired last night.
oh..20 minutes in, they were all over the use of napalm....
