George W. Bush is preparing for the final US-European Union summit of his presidency. The timing of his trip comes as many Europeans have begun to look beyond Bush, but he is promoting his agenda to the end of his term. Bush will push for stronger penalties against Iran to discourage Tehran from developing nuclear weapons. His talks with leaders will also cover climate change, the world food crisis, Israeli-Palestinian peace negotiations and Lebanon. He's also traveling to Germany, Italy, France, England and Northern Ireland.
