Did Britain pay too little attention to fighter cover at Taranto while Japan went too far with fighter suppression at Pearl Harbor?
Short answerNo; Taranto faced no comparable night-fighter threat, while Japanese aircraft actually encountered defenders at Pearl Harbor.
NotesBritain did not neglect a fighter threat comparable to the one Japan faced, and Japan did not overinvest in suppression. Taranto was a night operation against an Italian fleet without a meaningful night-fighter threat. Pearl Harbor was attacked in daylight and Japanese aircraft did encounter defending fighters. The different enemy capabilities made Japan's fighter-suppression effort prudent rather than excessive.
