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.

The temptation in any approaching crisis or conflict is, because people haven't got a clue what lies ahead, they're always searching into the past for some sort of pattern ... to galvanise the nation or their supporters and put themselves on a pedestal to sound Churchillian or Rooseveltian.
