Yes, very likely.
They knew the US Navy was the only thing that could keep them from dominating the entire Pacific (even in its "gutted" state in 1941, which BTW we still had one of the most modern navies in the world at the time), as the British and Australians were busy fighting Hitler and Mussolini in Europe and North Africa and didn't have the resources to spare for a two front war.
Hence the whole surprise attack to destroy as much of our Pacific fleet as possible in one blow.
Seriously, your posts lately have made me lose a great deal of respect that I had for you.
The US military was unable to mount a deterrent against the Japanese conquest well before '42.
That is one reason is why the Japanese were able to sweep down through SW Asia and the islands of the East Indies/Philippines.
The US was unable to put up any decent resistance.
We had pockets of areas but not enough to turn the tide; it was a delaying action for 2-3 years, buying time to rebuild.
The attack against the fleet was to ensure that there would be no direct Naval support to challenge the island hopping going on. The Japanese air cover in their push made it easy against what resistance was available. Had we lost the carriers also; New Zealand and Australia would have been isolated. the Japanese were already knocking on their door from New Guinea.
