British Prime Minister Churchill once said to him that if he had the choice between France and the United States, he would always choose the United States. Churchill's successor, Macmillan, prioritised the rebuilding of the Anglo-American "Special Relationship". With the American agreement to supply Britain with the Skybolt nuclear missile, de Gaulle thought that the United Kingdom would not go along with his vision for a West European strategically independent from the United States. He maintained there were incompatibilities between continental European and British economic interests. In addition, he demanded that the United Kingdom accept all the conditions laid down by the six existing members of the EEC (Belgium, France, West Germany, Italy, Luxembourg, Netherlands) and revoke its commitments to countries within its own free trade area (which France had not done with its own). He supported a deepening and an acceleration of Common Market integration rather than an expansion.
