Emperor Hirohito

A cataclysm became inevitable in the last months before Hiroshima.

By the summer of 1944, U.S. military power in the Pacific Theater had grown spectacularly. Beginning nine days after the D-Day invasion in France, American forces launched their largest attacks yet against the Japanese-held islands of Saipan on June 15, Guam on July 21, and Tinian on July 24.

Though war with Japan was expected momentarily, and four carriers of the Imperial Navy were ominously unaccounted for, no one thought to protect our most important Pacific base from surprise attack. Why?
