In "Kissinger: Volume I: The Idealist, 1923-1968," Niall Ferguson focuses on the complex life of Henry Kissinger, exploring his formative years and rise to prominence. The book delves into Kissinger's early experiences in Europe, his understanding of international relations, and his eventual influence on American foreign policy. Ferguson presents Kissinger as a figure deeply shaped by his historical and cultural background, impacting his views on global diplomacy.

The quote, "No one can predict how it will end because there is no precedent for it," reflects the unpredictable nature of international politics during Kissinger's era. Ferguson emphasizes that the world was entering uncharted territory, making it difficult to foresee outcomes in geopolitical strategies. This uncertainty underscores the challenges Kissinger faced as he navigated complex scenarios that had no historical parallels.
