Abstract: | In recent times, Pearl Harbor historiography has shifted towards the question of whether or not the Pearl Harbor attack could have been predicted through intercepted signals. The recent prodigious output of books and articles on this subject makes it necessary to reflect upon how the debate has developed. Some traditionalists (who believe that the Pearl Harbor attack surprised US and Allied authorities) continue to criticize revisionists (who believe that intercepted signals may have provided foreknowledge of the attack) using a blend of polemics and ad hominem criticism. That adversarial template began long ago with the first sharp criticisms of the work of revisionist historian Charles Beard. Similar criticisms of revisionists continue to the present day, but such criticisms are unfounded as relevant evidence concerning pre-Pearl Harbor signals intelligence, drawn from both archival and anecdotal sources, suggests that the revisionist thesis merits further scholarly attention. |
