Part I — The story
The story
Henry Kissinger, a refugee from Nazi Germany who rose to become US Secretary of State and National Security Advisor, was the most influential — and most controversial — diplomat of the twentieth century's latter half. He practised 'realpolitik': foreign policy based on practical power and national interest rather than ideology or morality. He engineered the opening of relations with China, pursued détente with the Soviet Union, and reshaped the global balance of power through patient, calculating strategy.
Kissinger thought in terms of systems, balance, and long time horizons, always asking how any move would shift the entire board and what the second- and third-order consequences would be. His approach is studied by strategists everywhere for its cold clarity about power and leverage. It is also deeply contested: critics hold him responsible for policies that caused great human suffering, and the moral costs of pure realpolitik are a permanent part of his legacy. Study him for strategic thinking at the highest level — and for the hard questions about ends and means it raises.

Frequently asked questions
What is 'realpolitik'?
Foreign policy based on practical power and national interest rather than ideology or morality — the approach Kissinger practised, as in the opening to China and détente with the USSR.
Why is Kissinger controversial?
Because the same cold strategic clarity that reshaped global power is held by critics responsible for policies causing great human suffering — the moral cost of pure realpolitik is a permanent part of his legacy.
