The legacy of the Bush-Blair years, and the post-9/11 madness, is never far from the surface of things - as much as Cameron or Obama might wish. This weekend there were calls for an inquiry into the death of Dr Kelly, the weapons expert whose whistle blowing cast doubt on some of the dodgy dossier claims pre-war - conspiracy theory has it he was not a suicide. The ongoing debate about the situating of a mosque proximate to the hallowed ground zero is another open sore - and a sign of the intolerance levels in America, a place barely healed by the election of its first African-American president. Now, Tony Blair - the man second-most-responsible for what deputy PM Nick Clegg has called an illegal war - is to donate all the money from his memoirs to a rehabilitation gym for wounded soldiers. This is admirable. A pity it is much too little too late. However, we must forgive Mr Blair, insofar as he seems to be seeking penance. I am not sure we need forget what he has done so easily.
