From the CNO:
ACTION: CinCAF, CinCPAC, Com 11, Com 12, Com 13, Com 15
INFO: Spenavo London Cinclant
Chances of favorable outcome of negotiations with Japan very doubtful. This situation coupled with statements of Japanese Government and movements their naval and military forces indicate in our opinion that a surprise aggressive movement in any direction including attack on Philippines or Guam is a possibility. Chief of Staff has seen this dispatch concurs and requests action adees [addressees] to inform senior Army officers their areas. Utmost secrecy necessary in order not to complicate an already tense situation or precipitate Japanese action. Guam will be informed separately.
