Absolutely!I will try to provide a detailed reply when I'm home and in front of a computer, but for now please consider the following. Pearl Harbor was not thought impossible. Ideas about ship to ship naval strikes had been circulating in military circles for at least two decades, and the British carried out a smaller version of Pearl Harbor at Taranto. The Japanese built on and evolved a concept that was widely discussed and considered.
EDIT: To circle this back to the topic of the thread, military planning and ideas about possibilities for future conflicts rarely pop out of the vacuum. The US should, and in fact does, plan for real conflicts based on a variety of scenarios. Things thought impossible do sometimes occurr, but these are extremely rare outliers. There is room for a legitimate discussion on planning for low probability high impact outliers but this is not the thread for it.
We know that the Japanese studied the successful RN attack on the Italian fleet at Taranto in 1940. Few ideas emerge whole, without a series of predecessors.
