The alleged coup plotters were middle-aged immigrants, who had made good lives for themselves in America over the course of decades, with careers, wives, children, savings, suburban houses, citizenship – the whole archetypal dream. They only visited the Gambia occasionally, if at all, and they had little connection to politics in their homeland. What could have possessed them to risk everything in a foolhardy attempt to topple one of the world’s strangest dictators? ... Jammeh is a tyrant out of caricature, a throwback to the African strongmen of the 1970s. He’s boasted that he will rule for “a billion years”. He’s adopted a ridiculous string of titles: “His Excellency Sheikh Professor Alhaji Dr Yahya AJJ Jammeh Babili Mansa.” (The last phrase translates to “conqueror of rivers”.) He’s posed as a fetishistic healer, claiming magical powers to cure Aids, asthma and diabetes, and has launched witch-hunts to root out enemy sorcerers. He’s deployed demagoguery against human rights groups, fanning popular hatred of gays, whom he has threatened to behead. He’s massacred protesters and disappeared political opponents. Through his feared intelligence service, he exercises crushing power over every aspect of the Gambia’s politics and economy, which subsists mainly on income from discount tourism and peanuts. ...
