Jimmy Carter, a former US president, has said that Washington knew about an abortive coup against Hugo Chavez, the Venezuelan president, in 2002, and that it may even have taken part. “I think there is no doubt that in 2002, the United States had at the very least full knowledge about the coup, and could even have been directly involved,” Carter said in an interview with Colombian El Tiempo newspaper published on Sunday. Carter said it was understandable that Chavez continues to blame the US for the failed attempt to overthrow him. Chavez was deposed by a civilian-military junta for about 48 hours in April 2002, before returning to power. George Bush, the then US president, denied any US involvement in the abortive coup and called on Chavez, who is critical of US policy, to “learn a lesson” from the attempted overthrow.
