The essay completes additional Amagi-class battlecruisers but refuses to erase the 1923 Great Kanto earthquake merely because it is inconvenient. Amagi is therefore still lost, while Atago and Ashitaka become the focus of the altered retention negotiations. This choice forces the author to work through how extra Japanese ships change the capital ships retained by Britain and the United States. Explicit assumptions and supporting references make the alternate history a tool for understanding the real treaty settlement.
