Correct.
The Important Information that had been communicated to DC in the run-up to the attack on Pearl Harbor was in an enormous "In Box" that had yet to be decrypted and processed.
I often think that the reason for the conspiracy theories about FDR and the attack on Pearl Harbor is an unwillingness to accept that this country could have been caught off guard to the extent that it was.
Gordon Prange's At Dawn We Slept is an absolute must-read on the subject of the attack; this should be considered a primer by anyone with even a cursory interest in the war.
He lays it all out (and at a time before the conspiracy theories took root, so he could hardly be considered an apologist for the FDR administration). The Japanese carriers, even those who did not participate in the attack, simply stopped any and all of their radio transmissions weeks before 12/07; US intelligence could not even hazard a guess as to where they might be, and the estimates were off by several orders of magnitude.
