There was also a lot of nasty work inbetween. The US was a supporter of decolonization of European empires in the 1940s and 1950s, which put us in conflict with France; De Gaulle was a horrifically small-minded nationalist who took special delight in being obstinate and sabotaging all attempts at cooperation with countries outside of France; and France resented the US taking the pre-eminent position in Europe despite not being European (or French).
