US President George W. Bush called on Iran and Syria to help stabilize the situation in Iraq, Israel Radio reported on Saturday morning. Bush made the statement in Sao Paolo, Brazil, during a tour of South American countries. Bush's visit overlapped with a large-scale protest against US policies arranged by Venezuelan President Hugo Chavez. Chavez said the timing of the protest, in which some 20,000 people participated, was a coincidence. "The US president today is a true political cadaver and now he does not even smell of sulfur anymore," Chavez said, alluding to Bush's waning years in office. "What the little gentleman from the North now exudes is the smell of political death and in a very short time he will be converted into cosmic dust and disappear from the stage."
