Brian decided to do a "citizen's audit" of American military actions by strapping on a backpack and traveling to Afghanistan, Iraq, Nicaragua (and other locales). And he did so without a predetermined itinerary or lodging--serendipitously finding places to stay and people to interview regarding how they feel about the U.S.'s military interventions in their countries.
I didn't even know there was couchsurfing or Airbnb in Afghanistan and Serbia!
Brian is living proof that way leads onto way. He'd talk to one person who'd say, "Oh, hey, my cousin's wife's uncle was a leader of the resistance. Let's meet up with him for dinner." And that guy would then say, "You need to talk to my former college friend who is the editor of the city newspaper." That kind of thing.
People spilled out their stories, and Brian captured them in this book. Captured the scale of death and misery. The pride. The loss. The hopes.
Brian's scope of knowledge about politics is astonishing. By the end of the book, he comes to some very important conclusions that all Americans should read in order to understand how violence affects us all.
