I think the mentality in the War Department of a two ocean navy really took flight when there was the call to revise the Rainbow plans in October of 1939. It just hasn’t become policy yet. I agree though that the decision to have a two ocean navy played a large roll in winning the war. It started the ramp up of tremendous ship construction well before the U.S. was officially at war. Not only did that help offset the losses in the Pacific when at one point we were actually down to just one operation aircraft carrier, but it also helped in that there was a tremendous surge of construction of the support ships that were vital to the war effort.
Very good points.
