Should a time-displaced USS Nimitz shoot down the Pearl Harbor strike or attack the Japanese carriers?
Short answerBoth: destroy the attacking aircraft first, then strike the Japanese carrier fleet while time and modern weapons permit.
NotesWith no return storm forcing an immediate departure, the modern carrier need not choose between defending Pearl Harbor and striking the Japanese fleet. The incoming aircraft would be destroyed first, followed by an attack on the Kido Butai. The carrier's modern air wing and weapons are sufficient for both missions in sequence. Without a time limit, the crew has an opportunity to destroy the raid and its launching force. The claim that this could end the Pacific War in one action belongs to the film's counterfactual premise, not to actual 1941 capabilities.
