Most of EUrope is still locked in appeasement mode, proving they're incapable of learning from their mistakes. They won't choose to fight unless they are being attacked. As for the population: millions around the world protested. Billions did not.
As for Blair and Kelly, the BBC and their little lying thug Andrew Gilligan didn't come off smelling like roses. Not all of Blair's problems stem from Kelly or the war. The economy has a lot to do with it too.
