Churchill and de Gaulle explores why Britain and France failed to cooperate after the Second World War. Drawing on declassified intelligence material, Matthew Hefler reveals that Winston Churchill opposed a lasting alliance with France. During the war he pursued an unofficial campaign in the Middle East, aiming to oust the French from the Levant, establish a ‘Greater Syria’ and create a Jewish state. Churchill continued this covert political action despite knowing that de Gaulle’s secret services had infiltrated the operation. Hefler reframes their relationship by showing how Churchill, to protect his unofficial policy, worked to discredit de Gaulle as a political force. Ultimately, Churchill’s secret statecraft meant sacrificing Franco-British relations and making de Gaulle an ‘enemy of Britain’.
