President Bush has arrived in Europe for a three-nation tour aimed at rebuilding transatlantic relations damaged by the US- led war in Iraq. Mr. Bush flew into Brussels on Sunday --the first stop on a five-day trip that will also take him to Germany and Slovakia. Officials in Brussels have mounted unprecedented security for the visit, which is also drawing protesters opposed to President Bush's policies. While in Brussels, the president will meet with European Union and NATO leaders for talks expected to focus on trans-Atlantic ties, the Middle East, and Iran's nuclear program. Mr. Bush will also meet separately with Iraq war opponents, including French President Jacques Chirac, German Chancellor Gerhard Schroeder and Russian President Vladimir Putin. President Bush is also due to hold talks with Iraq war allies, including British Prime Minister Tony Blair.
