And there was me thinking the Kennedys were of Irish extraction? Long time Catholics. I guess Sirhan thought we all look alike or some simplistic model such as "American, white, therefore must be an Israeli supporter".
Post Holocaust, maybe that wasn't too far off the mark? Nevertheless, Jeremy Isaacs' series, The World at War wasn't made until ~1972-73 and he wouldn't have bothered unless he had felt that too few people were aware of it, or were too young to have encountered tales of it (give or take that many servicemen, like my grandfather, just didn't want to talk, when asked what they did). I don't know if it was ever screened, in the USA, until the era of Discovery channel, where it almost never stops being re-shown (minus some truly horrific bits, where even blurring wouldn't help protect you from the concept being conveyed).
