I was taking all prints and I brought them to the Magnum meetings, trying the old Josef Koudelka trick: Give them to photographers, who are getting bored during the talks about the economics of the agency, to look through with a pen. They'll separate them in two piles. I started to find the core pictures that people seem to relate to.

Even though most people were disconnected from [travel ban], the moment amplified a fairly massive and somewhat irrational fear that exists in the populace at large.

That kind of unease, that melancholy, is of course partly my interpretation, but partly, I think, it's something that's really there [in America] as well. It resonates with this moment and the sort of alienation from the power structure a lot of people feel, as well as a certain amount of desperation, in the hope of disrupting the power structure so they can live better lives. I think in those ways, it's intimately connected to today.

I'm a constant editor. Every few months or so I make a ton of 4x6 prints. I put them on a magnetic board and I live with them for a while to see what bubbles to the surface. A lot of this was part of Disco Night originally, and I suddenly started realizing, "If I keep working on this because I'm not done and I put all that in Disco Night, how can this be one book? Is it going to be too long and bloated and crazy?".

I am still covering conflict to some degree. I was back in Iraq. I've covered quite a bit of the Israel and Palestine. But I'm not doing it with the kind of intensity I was before and I'm not seeking out the front line and the kind danger that comes with being at the edge of the war the way I used to.

I began to explore America in more general terms. I really started this work in 2009. I got the bulk of it done as I was easing out of Disco Night.

You find [reverberations from 9/11 ] in them most unexpected places, like graffiti on a wall. Sometimes it's a faded picture; sometimes it's a newspaper tacked to a wall. Sometimes it's weird paraphernalia related to it, home constructed paraphernalia. It resonates through society and continues to resonate today.
