The coup was engineered by Ojok, Museveni, and others acting under the general direction of Paulo Muwanga, Obote's right-hand man and chair of the Military Commission. The TPDF was still providing necessary security while Uganda's police force, which had been all but destroyed by Amin, was rebuilt, but Nyerere refused to help Binaisa retain power. Many Ugandans claimed that although Nyerere did not impose his own choice on Uganda, he indirectly facilitated the return to power of his old friend and ally, Milton Obote. In any case, the Military Commission headed by Muwanga effectively governed Uganda during the six months leading up to the national elections of December 1980.
