de Gaulle helped precipitate one of the greatest crises in the history of the EC, the Empty Chair Crisis. It involved the financing of the Common Agricultural Policy, but almost more importantly the use of qualified majority voting in the EC (as opposed to unanimity). In June 1965, after France and the other five members could not agree, de Gaulle withdrew France's representatives from the EC. Their absence left the organization essentially unable to run its affairs until the Luxembourg compromise was reached in January 1966. De Gaulle managed to make qualified voting majority (QVM) mechanism essentially meaningless for years to come, and halted more federalist plans for the EC, which he opposed. Six-Day War Having vetoed Britain's entry into the EEC a second time, in June 1967, he condemned the Israelis for their occupation of the West Bank and Gaza following the Six-Day War, saying "Israel is organising, on the territories which it has taken, an occupation which cannot work without oppression, repression and expulsions - and if there appears resistance to this, it will in turn be called 'terrorism'." This was a major change in French policy. Until then, France had been a staunch ally, helping Israel militarily and jointly planning the Suez Campaign in 1956. Under de Gaulle, following the independence of Algeria, France embarked on foreign policies more favourable to the Arab side, still a distinct aspect of French foreign policy today. Israel's leadership, stung by what it considered its capricious abandonment, turned towards the United States for military support. However, de Gaulle supported the principle of a just settlement for both the Arab and Jewish refugees of the Middle East within the framework of the United Nations. This was stated upon the adoption of UN Resolution 242, in his press conference of 27 November 1967 and contained in his letter to David Ben-Gurion dated 9 January 1968. Nigerian Civil War During Nigeria's civil war of 1967-1970, de Gaulle's government supported the Republic of Biafra in its struggle to gain independence from Nigeria. Despite lack of official recognition, de Gaulle provided covert military assistance through France's former African colonies. The United Kingdom opposed de Gaulle's stance, but he viewed the political position of the Igbo in Nigeria as analogous to that of the French Québécois living in Canada. Vive le Québec libre! In July 1967, de Gaulle visited Canada, then-celebrating its centennial with a world's fair,
