In his radio address on Saturday, President U.S. George W. Bush warned that there is likely to be tougher fighting to come in Iraq. And, as he did in his meeting at the White House Friday with Iraqi Prime Minister Ibrahim al-Jaafari, Bush urged Americans to share their confidence in a positive outcome to the war. "The Iraqi people are growing in optimism and hope," Bush said. "They understand that the violence is only a part of the reality in Iraq." The president told radio listeners his strategy for military success is to defeat members of Saddam Hussein's former regime and foreign and Iraqi terrorists and criminals responsible for the violence. At the same time, the United States is helping train Iraqi security forces so U.S. troops can eventually return home. "The terrorists' objective is to break the will of America and of the Iraqi people before democracy can take root," Bush said. --More 2120 Local Time 1820 GMT
