This is the most comprehensive perceptive and nuanced review to date of the foreign policy of the Lyndon Johnson era. It demonstrates US concern not just with the Soviet Union Europe and nuclear weapons issues but the overwhelming preoccupation with Vietnam which shaped policy throughout the world. During this period Johnson also faced a series of emergencies ranging from turmoil in the Congo to war in the Middle East to a perceived communist challenge in the Caribbean to a lingering hostage crisis in Asia. Using the most recently declassified documents it explains in thoroughly readable prose the intricacies of the foreign policy dilemmas that forced Johnsons Great Society domestic agenda into retreat.
