De Gaulle was targeted for death by the Organisation armée secrète (OAS), in retaliation for his Algerian initiatives. Several assassination attempts were made on him; the most famous took place on 22 August 1962, when he and his wife narrowly escaped from an organized machine gun ambush on their Citroën DS limousine. De Gaulle commented "Ils tirent comme des cochons" ("They shoot like pigs").[212] The attack was arranged by Colonel Jean-Marie Bastien-Thiry at Petit-Clamart.[213] Frederick Forsyth used this incident as a basis for his novel The Day of the Jackal. https://en.wikipedia.org/wiki/Charles_de_Gaulle

The Day of the Jackal is a 1973 British-French political thriller film directed by Fred Zinnemann and starring Edward Fox and Michel Lonsdale. Based on the 1971 novel The Day of the Jackal by Frederick Forsyth, the film is about a professional assassin known only as the "Jackal" who is hired to assassinate French president Charles de Gaulle in the summer of 1963.[2]

In February 1966, France withdrew from the NATO Military Command Structure, but remained within the organisation. De Gaulle, haunted by the memories of 1940, wanted France to remain the master of the decisions affecting it, unlike in the 1930s, when it had to follow in step with its British ally. He also ordered all foreign military personnel to leave France within a year.[227] This latter action was particularly badly received in the US, prompting Dean Rusk, the US Secretary of State, to ask de Gaulle whether the removal of American military personnel was to include exhumation of the 50,000 American war dead buried in French cemeteries.[228]

I would argue that a more likely reason that France pulled out of NATO in 1966 was that French Intelligence had informed De Gaulle that high level NATO staff members were actually behind many of the numerous assassination attempts on him that were never reported in the French and International Press, ostensibly for security reasons, prior to and after NATO's involvement in the November 1963 assassination of
President Kennedy.
