Foreign responses to Admiral-class carriers

Would converting Admiral-class hulls into Eagle-style carriers push the United States and Japan to respond?

They would probably respond, but funding, observation time, and the pace of design work would determine whether matching ships appeared quickly or years later.

Large British carriers would attract American and Japanese attention and probably prompt competing designs. Awareness would not create an immediate ship because budgets, design work, and the decision to watch British experience could delay the answer. Strategic pressure to respond still has to pass through the procurement timetable that turns pressure into hulls.
