 Behind the scenes the militaries of Tanzania, Sudan and Somalia had co-operated and contemplated to send a joint force of several thousand troops through the Kagera Salient into Uganda to topple Amin.The three countries propped up the exiled President and his forces instead and supported their invasion of Uganda in 1972, but they failed to dislodge Idi Amin.Somalia eventually would play mediator, and through the Mogadishu agreement, more war was averted.
