The evolution of how we recruit and train spies—starting with the OSS in the 1940s—and our changing expectations of what the job entails and what motivates those who sign up:

I remember him saying something like: “This is the only thing in the Army that you can volunteer for and then get out of if you change your mind.” That’s because we had signed up for something illegal, even immoral, according to some people, he said.

It was called espionage. We were not going to be turned into spies, he explained, but “case officers” — the people who recruit foreigners to be spies. Put another way, he went on, we were going to persuade foreigners to be traitors, to steal their countries’ secrets. We were going to learn how to lie, steal, cheat to accomplish our mission, he said — and betray people who trusted us, if need be. Anyone who objected, he concluded, could walk out right now.

He looked around. One man got up and left. The rest of us, a little anxious, stayed put.
