We discussed this also in my human rights class (which realy just ends up being discussions of all the politics we find of interest). Clinton lied about a sexual relationship, and he was impeached. Bush lied about starting a war of aggression, and no one seems to mind because September eleventh is like his "do whatever the fuck you want" card. Blair lied to the British people, and you know what? The British people got angry. They're not letting him off the hook nearly as easily as America has seemed to let off its president. They're demanding to be taken seriously.
Again, people wonder why I like the British. Seriously, it's not just the music.
