Since its independence in 1962, Algeria has always been considered as a leading advocate for Arab, African and Third World national causes. The young nation played a central role in anti colonialism, the Non Aligned movement, the call for restructuring of the international system, and the establishment of a new international economic order. All these factors have in many ways not only influenced Algeria’s foreign policy but also placed the country in direct confrontation with the United-States policy objectives and interests. On the political level, during the socialist year of Houari Boumediène’s presidency, Algeria’s position on the Arab-Israeli conflict, the Vietnam War, Cuba, has always caused dissension between the two countries. Nonetheless, if Algeria’s relations with the United States have been marked by misunderstandings and antagonism the Algerian president was also a pragmatist interested in developing economic ties with the United States. Even when Algeria decided to break diplomatic relations with the US during the Arab Israeli war of 1967 substantial commercial interests have been maintained mainly in the hydrocarbon sector. This paper will discuss the strategy and the objectives of Boumediène’s presidency in the conduct of Algeria’s Foreign Policy towards the United-States. It is a matter of showing why the regime decided to adopt a radical foreign policy mainly due to historical reasons and to the position of leadership in the Non Aligned movement.
