Using the Hull Note to trigger a fleet sortie

The Hull Note paired principles of territorial integrity, non-interference, commercial equality, and peaceful settlement with a proposed multilateral Pacific agreement. Its concrete terms required Japan to withdraw military, naval, air, and police forces from China and Indochina, abandon support for rival Chinese regimes, and accept changes to extraterritorial and trading arrangements. The United States in turn offered negotiations over frozen funds, trade, the dollar-yen rate, and a wider diplomatic settlement. From Tokyo's perspective, however, the weaker party was being asked to surrender far more of its existing policy than Washington. The alternate-history hinge is procedural rather than magical: attach a response deadline, begin fleet preparations while waiting, and issue sailing orders when no satisfactory reply arrives. That sequence makes a 6 December sortie the product of coercive diplomacy and prior mobilization, not a last-minute intuition.
