A later attack on Pearl Harbor could confront more regular radar operation and better air-defence discipline. An airborne combat air patrol is another possible obstacle to surprise. The discussion still allows a Japanese strike and a comparable level of damage, then questions whether the base would remain as exposed after more preparation. Repeating the historical plan therefore does not establish that it would produce the historical result.

Could a later Pearl Harbor raid achieve the same surprise?
More consistent radar use, stronger air-defence discipline, and combat air patrols could reduce the surprise available to a later Japanese attack.
