The Japanese reaction to the Allied ultimatum for unconditional surrender is... mokusatsu. This can be translated several ways, but all involve not giving a response. Meanwhile, materials for atomic bombs to be dropped on Japan are delivered to Tinian, though the ship making the delivery is sunk by a Japanese submarine days afterward. The active war continues in Burma and China, and the Potsdam Conference ends in Germany with the map of Poland very much re-drawn.
