You and Chez only seem to be interested in "what if's" that will hurt the US. What happened to the "other side of the coin"? The spotting report that totally destroys any hope of suprise on the 7th? Why no "speculation" on the equally far-fetched "possibility" of dawn on the 7th arising and KB finding a fully alerted US Fleet 10,000 yards to the windward planning live fire gunnery exercises? Very unlikely? Certainly! But NOT IMPOSSIBLE..., which seems to be your criterion. My suggestion was to keep the "what if's" fair and reasonable for both sides.
Whoa!!! You need to lay off whatever substance is giving you these paranoid delusions about this "what if". In no way, shape or form was my hypothesis meant to be present anyone's fanboy supposition. I have no idea why you would choose to take it so.
And no one is talking about a US CV being all alone up there. No one is talking about a surprise attack so devasting that no message could be sent. You may have been mislead by my use of the word "carrier" rather than carrier task group. It certainly was not meant to imply no other ships were present. I chose "carrier" for expediency's sake only. The same as someone might say "Hornet steamed to Japan to launch Doolittle's Raiders." Sure doesn't mean she was by herself. And it could be a rowboat with a radio for all I cared. I chose a carrier for the simple reason that it would have been the only type ship capable of inflicting damage on KB in return.
The original premise was "What if KB encountered a
US CV Task Group enroute Pearl Harbor? What would they have done?"
And the issue of surprise is exactly the question. Would Nagumo have thrown it away to sink a CV? Pure and simple. I think he would have, especially if he has been detected in return. Others don't think so. If he did attack, his reception at Pearl would most certainly have been a "little" warmer. Wait, let me rephrase that. His attack on Pearl Harbor would been hotly contested. Specific enough for you?
As far as why a CV TG would operate in that region, logic should have told US operational planners that the northern route offered the best chance of an enemy being able to approach the islands undetected. A look at the map clearly reveals that. The southern route contains too many shipping lanes for a covert transit and the US had several bases guarding the western route (Midway, Wake, Johnston, western HI islands, etc). So even though war hadn't started yet, it would have been very prudent to patrol ALL the approaches to Pearl.
And the other side of the coin is: "What would the US battlefleet have done in response?" Stay inport? Sortie towards safety? Sortie for sea room but remain near Pearl? Attempt to engage KB? Who knows?
These were the questions being asked. You chose to take it as a Jap fanboy "What if" conspiracy. Ridiculous.
