CARACAS, Venezuela -- Venezuelan President Hugo Chavez has ignited new controversy with his plans for "units of popular defense" throughout the country to defend it from a possible attack from "imperialism." Chavez, who has referred on many occasions to a possible U.S. invasion, said, "If imperialism ever has the idea of challenging Venezuela it would have to deal with Bolivar's people, who is prepared to defend their sovereignty, their motherland."
