Without Kissinger's work in the Middle East, with Sadat especially, I doubt if the Camp David Agreements five years later would have happened. His achievements over detente, the seeds of trust he sowed in a very distrustful and hostile Moscow, helped over a long period.

Kissinger was surely one of the very few statesmen to try to do something positive to break the log jam of the Cold War; to try to end the war in Vietnam; to bring a halt to the cycle of war in the Middle East.

Software options proliferate extremely easily - too easily, in fact - because too many options create tools that can't ever be used intuitively. Intuitive actions confine the detail work to a dedicated part of the brain, leaving the rest of one's mind free to respond with attention and sensitivity to the changing texture of the moment.
