The whole concept of isolationism in these modern days is weird. It was a thing in the 1930's. But after WW2, we were kind of all in.Just spent the last few nights reading an awesome book written by a B-17G radio operator, of his time during the war (and in training). 8h AF, lots of really mundane details, that matter only to those of us who ever strapped on a grey airplane (or in their time, green). Really good read, but he keeps talking about how his old man was an "isolationist" even after Pearl Harbor. Sounds a lot like the idiots from the tea party or MAGA. Dim wits who run their mouths when adults are talking.
It is pretty striking that more and more traditional Reagan-style conservatives are coming out against the current GOP nominee. IMO Gen Mattis needs to speak up with his experience as SecDef. More than a few quotes in a print interview.
