Kissinger initially supported the normalization of United States-Cuba relations, broken since 1961 (all U.S.–Cuban trade was blocked in February 1962, a few weeks after the exclusion of Cuba from the Organization of American States because of U.S. pressure). However, he quickly changed his mind and followed Kennedy's policy. After the involvement of the Cuban Revolutionary Armed Forces in the independence struggles in Angola and Mozambique, Kissinger said that unless Cuba withdrew its forces relations would not be normalized. Cuba refused.
