Idi Amin, the former dictator of Uganda, did not invade any country in 1979. However, it is worth noting that Amin was known for his aggressive foreign policy during his time in power from 1971 to 1979. In 1972, he ordered the expulsion of the Ugandan Asian community, which consisted of people of Indian and Pakistani descent. Additionally, Amin was involved in territorial disputes with neighboring countries such as Tanzania and Kenya. However, he was eventually overthrown in 1979 following a military invasion led by the Ugandan National Liberation Army and the Uganda National Rescue Front, supported by the Tanzanian army.
