clear. Some authors have proposed that dismantling refugee camps was a means of replenishing Rwanda's depleted population and workforce following the genocide; because the destruction of the camps was followed by forced repatriation of Tutsi regardless of whether they were Rwandan or Zairian. The intervention may also have been motivated by revenge; the Rwandan forces, as well as the AFDL, massacred retreating Hutu refugees in several known instances. A commonly cited factor for Rwandan actions is that the RPF, which had recently come to power in Kigali, had come to see itself as the protector of the Tutsi nation and was therefore partially acting in defense of its Zairian brethren. Rwanda possibly also harbored ambitions to annex portions of eastern Zaire. Pasteur Bizimungu, president of Rwanda from 1994 to 2000, presented the then-US ambassador to Rwanda, Robert Gribbin, with the idea of a "Greater Rwanda." This idea purports that the ancient state of Rwanda included parts of eastern Zaire that should actually belong to Rwanda. However, it appears that Rwanda never seriously attempted to annex these territories. The history of conflict in the Congo is often associated with illegal resource exploitation but, although Rwanda did benefit financially by plundering Zaire's wealth, this is not usually considered their initial motivation for Rwandan intervention in the First Congo War. Uganda As a close ally of the RPF, Uganda also played a major role in the First Congo War. Prominent members of the RPF had fought alongside Yoweri Museveni in the Ugandan Bush War that brought him to power, and Museveni allowed the RPF to use Uganda as a base during the 1990 offensive into Rwanda and subsequent civil war. Given their historical ties, the Rwandan and Ugandan governments were closely allied and Museveni worked closely with Kagame throughout the First Congo War. Ugandan soldiers were present in Zaire throughout the conflict and Museveni likely helped Kagame plan and direct the AFDL. Lt. Col. James Kabarebe of the AFDL, for example, was a former member of Uganda's National Resistance Army, the military wing of the rebel movement that brought Museveni to power, and French and Belgian intelligence reported that 15,000 Ugandan-trained Tutsi fought for the AFDL. However, Uganda did not support Rwanda in all aspects of the war. Museveni was reportedly much less inclined to overthrow Mobutu, preferring to keep the rebellion in the East where the former génocidaires were operating. Angola Angola
