This Friday marks the 65th anniversary of the bombing of Hiroshima, with the anniversary of Nagasaki's bombing on Monday. To protest the continued procurement of nuclear weapons, Think Outside the Bomb are camping near Los Alamos. Their website, thinkoutsidethebomb.
If you're not real outdoorsy, check out John Hersey's Hiroshima. It's an amazing book, which appeared as an article in the New Yorker's August 31, 1946 issue. In fact, it was such a powerful story, editors dedicated the entire issue to it, forgoing their cartoons or any other articles.
Another of my faves about the aftermath of World War II is John W. Dower's Embracing Defeat. It's not an uplifting book but it creates a vivid post-war world in your mind.
Of course, 65 is often cited as retirement age (though that's not exactly true these days), which gives Think Outside the Bomb's protest a little more of a "Happy Retirement Fat Man and Little Boy" feel.
