Philip Zelikow, writing in "Foreign Affairs", objected to Stinnett's claim that the Japanese naval code was being read at the time (the JN-25 code was changed shortly before the attack and was not decrypted again until May 1942), an objection also raised by Crane. A review posted on the U.S. Naval Cryptologic Veterans Association website addresses the intelligence issues in greater detail and disputes claims that the fleet was detected through direction finding; the author also criticizes Stinnett's use of testimony from Robert Ogg, originally identified as "Seaman Z" by John Toland in his 1986 book. Indeed, Ogg expressly denies saying what Toland quotes him as saying. In their annotations on the 1995 Pentagon study of the attack, Frederic Borch and Daniel Martinez, chief historian at the USS "Arizona" Memorial, also dispute these claims and call his claims "totally false".
