Idi Amin Dada: Life President of Uganda

In 1978, Idi Amin made the biggest mistake of his dictator career. He invaded Tanzania over a useless piece of land. The next Tanzania marched on Uganda, aided by the Ugandan-Ugandan exiles. They moved to unseat Idi from power. This didn't work, and did not turn back the Tanzanian army. So Idi Amin had to flee from power, first to Libya and then to Saudi Arabia.
