What if you just moved the carrier fleet from Pearl to San Diego?
Instead of introducing new TUV onto the board, you just shift it out of harms way. This would give the US a strong Pacific option, but also preserves these units to go either way if desired.
Admiral James O. Richardson would have approved of this concept. In fact it’s pretty much what he said to President Roosevelt in 1940. It didn’t turn out to be a good move career-wise in the short term (he was dismissed as CinCUS), but this wasn’t altogether a bad thing for him in the long run in view of what happened to his successor, Admiral Husband E. Kimmel.
