On 25 November 1987, United Nations Security Council Resolution 602 was passed, condemning Operation Moduler as an illegal violation of Angolan sovereignty. The resolution expressed dismay at the continued presence of SADF troops in Angola and called for their unconditional withdrawal. South African foreign minister Pik Botha flatly dismissed the resolution out of hand, citing the unaddressed issue of Cuban linkage. He promised that the SADF would depart Angola once FAPLA's Cuban and Soviet advisers had likewise been withdrawn, or when their presence no longer threatened South African interests.
