It's an interesting question, and as Dave's put it, founded in a period view that is fact based.
However as has been said, the
big trend of the war was decided essentially by American manufacturing and effort, which I for one am appreciative of as a vital contribution. We must remembr that once the US was entered total war, the Japanese could not win; and we must also remember they expected to arrive at a compromise peace - something the allies decided was not going to happen.

I have to disagree about "game -set- match,we'll be all speaking Japanese". It would be a terrible setback, but the result would have been the same. A victory for the U.S.A. and our allies. Our industrial might was and is overwhelming and as one WIXER puts it in his replies something about you cannot invade the U.S. as there would be a rifle behind every blade of grass.
In the real world there was no real intent by the Japanese to invade the US, and there was no way America would have been 'speaking Japanese' as they just weren't coming in reality. (It was never going to even get to a mainland invasion.) That's W.W.II allied propaganda; excusable then, misleading now. It's probably fair to say the Japanese misread the potential American change of attitude caused by their strike on Pearl Harbor - had they gone for a slower attrition based attack on the British Empire's eastern possessions and those of the occupied Dutch, the Isolationists (as Dave's pointed out) might have continued to put the brakes on US response, and the Japanese might've got what they wanted, which was colonies and empire under the euphemism of the 'Asian Co-Prosperity Sphere'.
Despite the tales of heroism in the early war defensive phase, we must remember that most of the allies' armed forces had outclassed aircraft that were just not combat ready, and aircrew who were mostly green or unaware of their combat ignorance (peacetime exercises were remarkably irrelevant) and easy pickings for the combat hardened Japanese pilots. The 'what setbacks where' was about the detail, and more dependant on combat hardening and
quality equipment arrival, IMHO.
Just a few comments,
