Relations were never easy between Charles de Gaulle and his British allies. De Gaulle mistrusted British motives, fearing a covert ambition to claim parts of the French Empire while France was so weak. Churchill's wife once advised him, "General, you must not hate your friends more than you hate your enemies".
For their part, Churchill and Roosevelt were never wholly convinced of the value of de Gaulle to the Allied war effort, and frequently came close to cutting off their support.
Consequently, Gaullist resistance groups rarely cooperated with SOE initiatives, or communist or maquis resistance groups, preferring to work independently against their own targets, under orders from de Gaulle in London.
Gaullism was also a political movement based upon General de Gaulle’s nationalist ambitions for France. It became political reality when he was inaugurated President in 1959, leading to France's withdrawal from NATO and the development of an independent nuclear deterrent.
