Dubya opted to demonstrate his contempt for the entire population of the planet with the phrase "Goodbye from the world's biggest polluter", a big smile and a celebratory punch of the air, as he left the dumbfounded G8heads to return to his planet-razing agenda at home. What is there to say. It's hard to satirise someone who demonstrates that level of open, blase contempt. He might as well have bared his arse and given the assembly the finger. I await the footage on YouTube.
