Finally, you know, you get a great idea, you plan and plan and plan for it and then you want to show off your cool torpedoes that work at shallow depth and great airstrikes at the enemy ports and when you show up, they're gone. Sometimes life is not fair.
I suspect that this raid on Pearl Harbor is pre-scripted but, if possible, there should be some adjustment made if the US is already in the war (even if it is not at war with Japan). Make it a bit more random.
