However, he opposed any development of a supranational Europe, favouring Europe as a continent of sovereign nations. De Gaulle openly criticised the United States intervention in Vietnam and the "exorbitant privilege" of the United States dollar. In his later years, his support for the slogan ""Vive le Québec libre"" and his two vetoes of Britain's entry into the European Economic Community generated considerable controversy in both North America and Europe. Although reelected to the presidency in 1965, he faced widespread protests by students and workers in May 1968, but had the Army's support and won an election with an increased majority in the National Assembly. De Gaulle resigned in 1969 after losing a referendum in which he proposed more decentralisation. He died a year later at his residence in Colombey-les-Deux-Églises, leaving his presidential memoirs unfinished.
