Clark spends the first half of the next book, "Executive Orders", serving as an instructor for CIA field officers in training. Early in the novel, Jack Ryan, the new President, issues a presidential pardon to John Terence Kelly for his several murders. This clears his name and personal honor, but he will continue his career as John Clark. Towards the end of the book, he and Chavez are returned to the field and ordered to discover who is responsible for an Ebola attack on the United States, an action they quickly trace to the new United Islamic Republic (comprising Iran and Iraq). With the cooperation of the Russian SVR, they are infiltrated into Tehran, where they laser-designate the home of UIR dictator Mahmoud Haji Daryaei so that Air Force stealth aircraft can destroy the house.
