A Mark Steyn (again!) remembrance:
But what he really was was a psychopath. In eight years, more than 300,000 Ugandans were killed. He enjoyed personally decapitating his enemies, and on one occasion he and a few family friends passed a pleasant farewell dinner with the severed heads of two opponents propped up at their places round the table. He had the second of his five wives murdered and dismembered, and then ordered the pieces retrieved from a burlap sack and stitched together so he could show her off to their children. The expatriate community he regarded as mainly a source of potential hostages, such as the adventurer and writer Denis Hills, whom he arrested and sentenced to death. After being advised to do so by God, he expelled all the Asians and destroyed his country’s economy. Then he decided to invade Tanzania, and that was the end.
A convert to Islam, he escaped to Saudi Arabia, where he’s been on “pilgrimage” ever since, living on a stipend from the royal family. At least in this instance, unlike their more recent subventions, the House of Saud began giving money to a mass murderer after he’d stopped killing.
