How to commemorate an important anniversary of the country in which you’re posted when it marks a low point in the bilateral relationship? World War II came to an end when Imperial Japan announced its surrender on August 15, 1945; officials from its government signed the Japanese Instrument of Surrender on September 2 aboard the USS Missouri. It was the end of a series of losses for Japan, including the detonation of an atomic bomb over Hiroshima on August 6, the declaration of war on Japan by the Soviet Union on August 8, and the launch of a second bomb on Nagasaki by the U.S. on August 9.

Fifty years later, American diplomats in Japan struggled with acknowledging the events of that fateful year in a way that would strengthen ties with an enemy-turned-ally yet not minimize the sacrifices of Americans who fought in the war.
