Yup, none of this is particularly unknown or secretive for people who look and not interested in deliberate deception (Khomeini was delivered by Air France after all!) Yes, more specifically, Shah was an ally to Nixon and had put his eggs in that basket (to the degree that he attended Shah's funeral.) Once the tide turned and Ford lost, shit quickly hit the fan (a bit resembling how Biden treated MBS.)

The other funny and ironic thing is Shah was instrumental in mediating and shaping the deal between Sadat and Israel, but somehow he got the short end of the stick and was branded an asshole authoritarian dictator by US leftist media (see Mike Wallace 60 mins from 1976[1] for example) and Carter got the Nobel Prize.

P.S. for fun, compare to Wallace's attitude when he sat down with Khomeini only a few years later, with questions submitted and vetted in advance[2]! Oh well, how history is written and rewritten...
