To provide a better understanding of Anglo-American relations at a pivotal moment, this volume provides all the correspondence between Harold Wilson and Lyndon B. Johnson from the time Wilson became Prime Minister (October 1964) until Johnson stepped down as President (January 1969). Whilst the United States was a superpower on the rise and Britain a declining influence on the world stage, the letters reveal that Johnson was eager for international allies and that Wilson possessed an independence which belies his image as a puppet of the President.
