Tony Blair's face says it all. It is etched with ruts and gullies where once there were laughter lines and humane creases. His cheeks have fallen in. The mental, political and emotional traumas of the last six months have left their indelible mark. He is the dedicated multilateral internationalist who has hitched his star to the least multilateral U.S. administration in modern times. He is the pro-European who has triggered the profoundest split in the European Union. He is the third-way progressive whose closest foreign ally despises third-way progressives. He has divided his party and the British liberal left over the lack of legitimacy of war in Iraq, and he shares with George W. Bush all the problems of reconstruction in Iraq but holds negligible leverage.
