Anti-American Venezuelan President Hugo Chavez greeted the resignation of US Defence Secretary Donald Rumsfeld on Wednesday with a suggestion that President George W Bush should follow him. “Heads have started to roll. The president should resign on moral grounds,” he told a news conference after an aide passed him a note with word of the resignation. “Rumsfeld should go to jail.” Chavez has a running feud with Bush, whom he calls the devil. He said the Democrats’ victory in mid-term elections on Tuesday was a vote against Bush’s Iraq war policy, which he hoped meant the United States would rein in its “imperialism.” Senior US officials say the leftist Venezuelan president is a threat to regional stability.
