As you all know, Kissinger is the architect of modern US foreign policy since Richard Nixon's administration. Despite his age (in his 80's), Kissinger was also invited to the State dinner at the White House during Chinese President Hu Jintao's visit to the US. This shows Kissinger's highly regarded status. I dare to say that he still influence current US foreign policy TODAY.
This book covers modern periods starting with pre-WWI times. It explains why Europe plunged into WWI and how the war redefined Europe, and largely Germany. And then it takes us thru the inter-wars period when Hitler rose, how Churchill saw through Hitler's intentions and how American isolationism was changed by Pearl Harbor...etc. Basically it was a comprehensive Western History from WWI to present day.
