71 years ago this week the United States of America became the only nation thus far to use atomic weapons in an act of war. Well, "act of war" may need to be in quotes, but that's an entirely different argument to be had. Whatever your feelings on the dropping of the bombs -- and there are plenty of people who were involved who regret it, and many who do not -- I highly recommend John Hersey's famous New Yorker piece from 1946 to accurately visualize just what the tragedy of Hiroshima consisted of.
Though you will not be able to accurately visualize just what the tragedy of Hiroshima consisted of. One of the main themes of Alain Resnais 1959 drama Hiroshima mon Amour is that the tragedy is ineffable. Despite that, the films explores and contrasts the tragic backstories of both its main characters, characters who apparently decide that their tragedies are equal. They may be in terms of personal definition, but certainly not objectively, which leaves me with a bad taste in my mouth. But it's still a beautiful film, and defined the film grammar still used for non-narrative storytelling in film.
