His legacy forever linked to an unpopular war, President George W. Bush flew under intense security to Iraq on Sunday where he called the nearly six-year conflict hard but necessary to protect the United States and give Iraqis hope. "The war is not over," he declared. Bush was reminded of the intense opposition to his policies when a man threw two shoes at him - one after another - during a news conference with Iraq Prime Minister Nouri al-Maliki. Bush ducked both throws, and neither man was hit. "All I can report is a size 10," Bush joked.
