As coincidence had it, I stumbled upon the HBO-produced documentary White Light, Black Rain: the Destruction of Hiroshima and Nagasaki yesterday afternoon. Since it was Victory Day, the 62th anniversary of Japan's surrender during World War II, the timing was poetic.
Like the young Japanese interviewed at the start of the documentary, many Americans have little sense of the incredible devastation unleashed by this use of atomic weapons. Students of history can continue to debate whether this was necessary and whether the bombs would have been used against a non-Asian nation.
Watch this powerful documentary, though (available on HBO On Demand), particularly the interviews with the survivors, and you will gain an enhanced appreciation of the sizeable human capacity for destruction -- and the urgent need to guard against it.
