It’s spy vs. spy vs. spy

Spying is a secret world which strives mightily to stay out of the public eye. But in an age of almost limitless electronic surveillance, that’s become much harder to do.

Just in the past year, three men identified as Russian military intelligence officers were accused of poisoning a former spy, his daughter, and two others, using a deadly nerve agent. A Russian woman acting as a graduate student admitted to U.S. prosecutors that she was an agent for Russia while cozying up to officials in the National Rifle Association and the Republican Party. And this week, former Acting FBI Director Andrew McCabe said that he opened a counterintelligence investigation into whether the president might have been acting on behalf of Russia after Trump fired McCabe’s boss while the FBI probed that country’s meddling in the 2016 U.S. election.

Suddenly, the topic of spies and spying dominates newsfeeds. Yet much of what the public and even policymakers know about this complicated subject is shaped by old James Bond films or John le Carré novels — and that needs to end, according to Calder Walton, Ernest May Fellow in History and Policy at Harvard Kennedy School (HKS).

Walton studies intelligence history and international relations, and co-runs the Applied History Project at HKS. He was recently named general editor of “The Cambridge History of Espionage and Intelligence,” to be published by Cambridge University Press in 2022. The three-volume work will document for the first time the vast and largely opaque record of how undercover information-gathering has been used and misused in conflicts from the ancient world through the cyberwarfare of the present.

The Harvard Gazette’s Christina Pazzanese asked Walton to help contextualize the FBI’s Russia investigation and the role other intelligence agencies may be playing in it, and to explain how intelligence and espionage have changed — and remained unchanged — since their earliest days.

Christina Pazzanese: First, what is the difference between espionage and intelligence?
Calder Walton:  Espionage traditionally refers to human spies and spying. Intelligence is much broader. It can mean human intelligence, but it also can mean
