In a 1965 speech justifying the war in Vietnam, Lyndon B Johnson argued that the goal was to ensure “every country can shape its own destiny” since only in such a world could the US secure its own freedom. However, he also admitted “such were infirmities of man that force must often precede reason, and the waste of war, the works of peace”.

It was the kind of elegant justification of the country’s moral mission to which successive US presidential speechwriters have turned at times of war.
