As the Allied armies closed in on the German capital in 1945, the complications for ending the war in Europe paled, in comparison with the difficulty of forcing a Japanese surrender. For the Japanese military, the concept was unthinkable, a state of mind confirmed by the hundreds of thousands of Japanese servicemen who had already been killed, rather than giving up a hopeless contest. 

the bomb goes off at Nagasaki
About fifteen minutes after the detonation of the plutonium bomb over Nagasaki, civilians on a nearby island stand not far from the pyrocumulus cloud, seemingly oblivious to it.  

The great popularity of the new movie Oppenheimer reveals the enduring fascination with the atomic attacks on Hiroshima and Nagasaki seventy-eight years ago.

In this issue, we look comprehensively at the use of those weapons and the struggle to end the war in Asia, which many people don't realize caused well over 20,000,000 deaths, mostly of civilians, and more than 100 times the horrific toll of the atomic bombs. (See “Counting All The Dead” here.)
