How victory at Pearl Harbor could reshape Pacific command

How would an American victory over the Pearl Harbor strike force change the Pacific campaign and naval command?

Japan's offensive timetable would collapse, Kimmel would probably remain in command, and Nimitz would likely receive a different operational assignment.

In this counterfactual, losing the Kido Butai at Pearl Harbor would leave Japan unable to execute its historical offensive sequence against an intact American battle fleet and carrier force. That makes later island campaigns less likely to unfold in their familiar form. A victorious Admiral Kimmel would also be politically and professionally difficult to replace immediately after winning the battle. Nimitz might instead become a task-force commander or fill a role that historically went to Halsey, illustrating how one operational result can reorder the command structure as well as the campaign.
