Venezuela, with the world's largest oil reserves, is in chaos after weeks of increasingly bloody violence on city streets and in middle-class neighborhoods. Protests that began three weeks ago in the city of San Cristobal have spread to Caracas and other parts of the country. Opponents blame the Socialist government for destroying the economy, creating a new elite and distracting attention by cracking down on legitimate protest. At least 14 people have been killed with 150 or more injured. President Nicolás Maduro, heir to the late Hugo Chávez, says "fascists" supported by the US are intent on staging a coup. Now, Maduro is calling for a "peace conference" tomorrow — hoping to be joined by Henrique Capriles, the state Governor he defeated in last year's elections. How did the current violence begin? Does the US really want "regime change?" Will energy supplies be affected worldwide?
