In a June 2010 interview for The New York Times, when asked by photojournalist Michael Kamber about Infidel, the book he did with Chris Boot that was about to be published, Hetherington commented on the level of danger he encountered when working on it: "The first time I went to Afghanistan, in 2007, the world was very much focused on Iraq. People had forgotten – and now we have come to accept – that the Afghan war was going out of control. When I got to the Korangal Valley, and there was lots of fighting going on, it completely surprised me. I was gobsmacked. At the end of October 2007, 70 percent of American bombs being dropped were in that valley, and the casualty rate was at 25 percent wounded. So the images I made were very action oriented. Photojournalism. Reminiscent of classical war photography. I did that because I wanted people to see that there was a lot of fighting going on.
