A comprehensive review of Kissinger up to 1991 offers a detailed look at his remarkable career. While it encompasses various aspects, it substantially focuses on his crucial position during the Nixon/Ford presidencies. Kissinger is widely regarded as a confirmed balance-of-power diplomat. His ability to navigate the complex international political landscape with finesse was truly remarkable. However, his secretive approach was sometimes a double-edged sword. On one hand, it allowed him to conduct delicate negotiations and achieve significant外交 breakthroughs. On the other hand, it also led to criticism and accusations of being too secretive and unaccountable. Additionally, Kissinger was a man with a large ego. His self-confidence and assertiveness sometimes rubbed people the wrong way. Nevertheless, his contributions to American foreign policy and international relations cannot be ignored.
