A few weeks ago in Guatemala, I participated in a long-overdue commemoration. September 14 was the one-hundredth anniversary of the birth of President Jacobo Árbenz, a former army officer who was elected in 1950, then ousted in 1954 in a coup organized by the CIA, and replaced by a military junta. His name has been taboo in Guatemala for most of the time since then. Many in the ruling elite still consider the causes he championed—land reform above all—repugnant and mortally dangerous. September’s commemoration included speeches, conferences, and a vote by the city council in Quetzaltenango, where Árbenz was born in 1913, to name the local airport in his honor.
