President Mobutu Sese Seko of Zaire accused Angola, Cuba, and the Soviet Union of sponsoring the rebels. Motivated by anti-Communism and by economic interests, the Western Bloc and China sent assistance to support the Mobutu regime. The most significant intervention, orchestrated by the Safari Club, featured a French airlift of Moroccan troops into the war zone. This intervention turned the tide of the conflict. U.S. President Jimmy Carter approved the shipment of supplies to Zaire, but refused to send weapons or troops and maintained that there was no evidence of Cuban involvement.
