From a book I found, while looking for more information on this guy;

The 12 th January 1970 date of this second phone-call suggests one likely subject of concern relating to Kissinger, Pompidou, Violet and American aviation industrialist Kelly: a major French intervention in Middle Eastern politics via the January 1970 sale by Pompidou of over one hundred Dassault Mirage 5 fighter- bombers to the new Libyan regime

And:

Dassault himself was none too happy about the sale of Mirages to Libya; a confidential South African diplomatic communication from their ambassador in Cologne dated 16 th January 1970 discusses an indirect approach to South Africa by Dassault to enquire "i) whether South Africa would have any interest in purchasing further Mirages for the use of the S. A. A. F. ii) if not whether South Africa would be prepared to acquire Mirages for re-export to Israel [...] Dassault is pro-Israeli in sympathy and is much concerned at the projected sale of 50 Mirages to Libya. If South Africa were prepared to place an additional order for Mirages [...] Dassault would be able to plead difficulty in supplying Mirages to Libya"

Interesting...

The group the book is referring to is Le Cercle occasionally called the Pinay Group or Pinay Society - a right-wing bilderberg.

Im sure the Dassault they are refering to is his father since Olivier would have been 19 in 1970.
