In the late 1980s, Ould Taya had established close co-operation with Iraq, and pursued a strongly Arab nationalist line. Mauritania grew increasingly isolated internationally, and tensions with Western countries grew dramatically after it took a pro-Iraqi position during the 1991 Gulf War. During the mid-to late 1990s, Mauritania shifted its foreign policy to one of increased co-operation with the US and Europe. It was rewarded with diplomatic normalization and aid projects. On 28 October 1999, Mauritania joined Egypt, Palestine, and Jordan as the only members of the Arab League to officially recognize Israel. Ould Taya also started co-operating with the United States in anti-terrorism activities, a policy that was criticized by some human rights organizations. (See also Foreign relations of Mauritania.)
