Israel's victory in the 1967 Six-Day War and subsequent occupation of the Sinai and West Bank alienated it diplomatically from much of the Third World and African states. Black nationalist movements then began to see it as a colonial state. At the same time, in South Africa, Israel became the object of widespread admiration, particularly among the country's political and military leadership. The editorial of "Die Burger", then the mouthpiece of the South African Nationalist Party, declared: "Israel and South Africa are engaged in a struggle for existence... The anti-Western powers have driven Israel and South Africa into a community of interests which had better be utilized than denied." In 1973, the Organization of Petroleum Exporting Countries (OPEC) instituted an oil embargo against Western nations as way of punishing them for supporting Israel; in doing so, OPEC sought support from other international groups to strengthen its impact. Arab states and black African nations formed a working alliance at the United Nations that sought both to criticize the two countries with UN resolutions and establish that the two develop close relations. Due to this alliance with the Arab world, many African countries broke off relations with Israel and did not consider restoring them for decades.
