http://www.cnbc.com/id/23133870 The U.S. remains the No. 1 buyer of Venezuelan oil, and Chavez relies largely on U.S. oil money to stimulate his economy and bankroll social programs that have traditionally boosted his popularity. Some analysts say it would make little sense for Chavez to follow through on his threats because Venezuela owns refineries in the United States that are customized to handle the South American countryâs heavy crude. WHAT do you guys think? bluffing?
