Venezuelan President Hugo Chavez criticized the United States for recent remarks about his role in Latin America, saying in a Sunday broadcast from Cuba that it is the policies of the U.S. government that are harming the world, not his own. Chavez spoke alongside Cuban President Fidel Castro during his weekly television and radio show from the western tip of the island, flaunting the close ties between the two leftist leaders that U.S. leaders say are threatening democracy in the region. "The grand destroyer of the world, and the greatest threat ... is represented by U.S. imperialism," Chavez said.
