Dr Kissinger said the 11 September attacks shattered a period of indolence and self-satisfaction. "The US public still doesn't understand why exactly we were attacked and what precisely it is that we are supposed to do, and that has generated an extraordinary sense of divine unity that I have never seen - even after Pearl Harbour - to this emotional extent," he said. He told an audience of journalists, politicians and policy makers that there is now an " extraordinary opportunity" to construct a new world order for the 21st century.
