Chances of favorable outcome of negotiations with Japan very doubtful X 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 X Chief of Staff has seen this dispatch concurs and requests action adees to inform senior Army officers their areas X Utmost secrecy necessary in order not to complicate an already tense situation or precipitate Japanese action X Guam will be informed separately.
