Hmm just speculating here but something struck me while reading your posts. you Theorize Jacqueline might be French intelligence. We know Joe was diddling Valerie while still married to Jaqueline, and it was at this time that Valerie told Joe she was CIA.
But, what if Jaqueline knew Valerie was CIA, and what we have here is a little social engineering. Once Valerie tells Joe she is CIA, Jaqueline and Joe basicallyy own her. Thus providing the reason Valerie would sayyy "hey how about we send my husband to Niger".
If I were really to indulge myself into a complete conspiracy theory I'd say "Could be" Or better yet, maybe Jacqueline and Valerie are one and the same person! If she outed herself to him she may have needed to end Jacqueline's "life" and begin a new one as Valerie.
It would be a hell of a stretch but aren't the CIA supposed to be able to do stuff like this?
Jacqueline doesn't seem to exist anywhere so maybe she was wiped clean except for a few seemingly minor places.
Of course I'd just be gussing at wind directions here and I really don't want to turn this into something like that.
I'd rather just vet out what we have here to ensure it's correct and true.
