Harrison's reputation for giving "early warning" of foreign policy crises was well established during his career as a foreign correspondent. In his study of foreign reporting, "Between Two Worlds", John Hohenberg, former secretary of the Pulitzer Prize Board, cited Harrison's prediction of the 1965 Indo-Pakistan War 18 months before it happened. Hohenberg wrote: "What Harrison foresaw came to pass, and when it happened, American editors suddenly rose up in their wrath – as they always do at such times – and demanded, 'why weren't we told about all of this?' They had been told at great length, but because too many editors were bored with a place like India, they weren't listening." Terming Harrison "one of the few correspondents in all of Asia who was able to maintain a balanced point of view," Hohenberg called him a model of the "first-rate correspondent who knows the past of the area to which he is assigned, writes with clarity and meaning of the present and has an awareness of the future."
