Rwandan President Habyarimana was aware of the increasing number of Tutsi exiles in the Ugandan Army and made representations to President Museveni on the matter. At the same time many native Ugandans and Baganda officers in the NRA began criticising Museveni over his appointment of Rwandan refugees to senior positions. He therefore demoted Kagame and Rwigyema in 1989. They remained "de facto" senior officers but the change in official status, and the possibility that they might lose access to the resources of the Ugandan military, caused them to accelerate their plans to invade Rwanda. In 1990 a dispute in south-western Uganda between Ugandan ranch owners and squatters on their land, many of whom were Rwandans, led to a wider debate on indigeneity and eventually to the explicit labeling of all Rwandan refugees as non-citizens. Realising the precariousness of their own positions, the opportunity afforded by both the renewed drive of refugees to leave Uganda, and the instability on the Rwandan domestic scene, Rwigyema and Kagame decided in mid-1990 to effect their invasion plans immediately. It is likely President Museveni knew of the planned invasion but did not explicitly support it. In mid-1990 Museveni ordered Rwigyema to attend an officer training course at the Command and General Staff College in Fort Leavenworth in the United States, and was also planning overseas deployments for other senior Rwandans in the army. This may have been a tactic to reduce the threat of an RPF invasion of Rwanda. After two days of discussion Rwigyema persuaded Museveni that following years of army duty he needed a break and was allowed to remain in Uganda. Museveni then ordered Kagame to attend instead. The RPF leadership allowed him to go, to avoid suspicion, even though it meant his missing the beginning of the war.
