Diffal succeeded the late Drefsab as Chief of Intelligence for the Race's Conquest Fleet on Tosev 3.[1] He served in that position from the time of Drefsab's death until the Peace of Cairo and well beyond, even past the arrival of the Colonization Fleet. He was not as capable at the task as had been his predecessor; it was under Diffal's watch that Straha was able to defect to the United States, for example.[2] He later personally admitted lacking Drefsab's ability to think, but did the best he could.

In 1965, Diffal was part of the commission the Race assembled to study the actions of US President Earl Warren's decisions to attack the Colonization Fleet in 1962, and to then allow the destruction of Indianapolis rather than surrender his country's space program.[3] Much of his time was spent arguing with the newly returned Straha, whose time in the USA led to knowledge and observations that were contrary to Diffal's conventional wisdom.[4]
