The Shokaku class belonged to a strategic debate larger than carrier design. Mitsumasa Yonai could support resistance to American pressure while also warning that Japan might win an opening battle but could not win the resulting war. Projecting strength seemed necessary to preserve Japan's position, yet every stronger signal increased the chance that foreign or domestic politics would call the bluff. Shokaku and Zuikaku were therefore both military instruments and products of a narrowing political timetable before Pearl Harbor.
