In 1988, Roosevelt published a memoir called "For Lust of Knowing: Memoirs of an Intelligence Officer", where he mentions his wartime service as an Army intelligence officer in Morocco, Iraq and Iran. He is much more circumspect in describing his time with the CIA, adhering so strictly to his oath to keep the CIA's secrets that he did not even identify the countries where he had served. And although he was happy to tell interviewers that they could figure it out from his entry in "Who's Who in America", he also was quick to explain that some Americans have forgotten what an oath is and that he would not break his even if the government told him to. Even still, evidence shows there was concern within the US government about the public knowledge of the contents of his book. President Ronald Reagan states in his diary that he was advised against holding a public White House reception for Roosevelt, so as to not promote his book. He does not state who specifically advised him on this matter.
