I lived through those times,too but never connected the Jackie/French love affair with Viet Nam.Chilling thought..but it makes sense.
Maybe I paid more attention, then you did, or was just a wee bit more aware of the subtle details. Who knows ? Anyway, I come from a long line of news/current events/political junkies and that's a good part of the topics,that were always hashed over the dinner table/get togethers. Perhaps I picked the info up there. *shrugs*
In any event, it's true, an historical fact, and evedently, something most people seem to not know. LOL
