September 13, 2019 "Information Clearing House" -  Book a suite in a luxury hotel in Moscow, send the room number encrypted to a pre-determined mobile number and then wait for a return message indicating a precise time: Meeting Edward Snwoden is pretty much exactly how children imagine the grand game of espionage is played.

But then, on Monday, there he was, standing in our room on the first floor of the Hotel Metropol, as pale and boyish-looking as the was when the world first saw him in June 2013. For the last six years, he has been living in Russian exile. The U.S. has considered him to be an enemy of the state, right up there with Julian Assange, ever since he revealed, with the help of journalists, the full scope of the surveillance system operated by the National Security Agency (NSA). For quite some time, though, he remained silent about how he smuggled the secrets out of the country and what his personal motivations were.

Now, though, he has written a book about it. It will be published worldwide on September 17 under the title "Permanent Record." Ahead of publication, Snowden spent over two-and-a-half hours patiently responding to questions from DER SPIEGEL.

DER SPIEGEL: Mr. Snowden, you always said: "I am not the story." But now you've written 432 pages about yourself. Why?

Edward Snowden: Because I think it's more important than ever to explain systems of mass surveillance and mass manipulation to the public. And I can't explain how these systems came to be without explaining my role in helping to build them.

DER SPIEGEL: Wasn't it just as important four or even six years ago?

Snowden: Four years ago, Barack Obama was president. Four years ago, Boris Johnson wasn't around and the AfD (Germany's right-wing populist party Alternative for Germany) was still kind of a joke. But now in 2019, no one is laughing. When you look around the world, when you look at the rising factionalization of society, when you see this new wave of authoritarianism sweeping over many countries: Everywhere political classes and commercial classes are realizing they can use technology to influence the world on a new scale that was not previously available. We are seeing our systems coming under attack.

DER SPIEGEL: What systems?

Snowden: The political system, the legal system, the social system. And we have the proclivity to think that if we get rid of the people we don't like, the problem is solved. We go: "Oh, it's Donald Trump. Oh, it's Boris Johnson. Oh, it's the Russians" But Donald Trump is not the problem. Donald Trump is the product of the problem.

DER SPIEGEL: A system failure.

Snowden: Yes. And that's why I'm writing this book now.

DER SPIEGEL: You write that you wanted to tell the truth. What was the biggest lie people told about you?

Snowden: Oh, God, there's a zillion of those. The biggest was ?

DER SPIEGEL: ? that you are a Russian spy?

Snowden: Not even that one, but that it was my plan to end up in Russia. Even the NSA admits that Russia wasn't my intended destination. But people repeat it because it's guilt by association. It's part of this typical warfare, that is going on at the moment. The facts don't matter. What you know is less important than what you feel. It's corrosive to democracy. Increasingly we cannot agree about things. If you can't even acknowledge what is happening, how can you have a discussion about why it is happening?

DER SPIEGEL: While writing, did you discover any truths about yourself that you didn't like?

Snowden: The most unflattering thing is to realize just how naïve and credulous I was and how that could make me into a tool of systems that would use my skills for an act of global harm. The class of which I am a part of, the global technological community, was for the longest time apolitical. We have this history of thinking: "We're going to make the world better."
