Were the Japanese so full of themselves to think they could win a war against America? I don't think so, there aim was to deliver a blow that would slow down there entry in to the war and full offensive operations but bad luck hit Japan at Peal as the American carriers were at sea and at Midway even more bad luck.

It seems to me the Japanese wanted to dig in hard on what they captured and after some bitter fighting and heavy loses to America they would sit down and draw up some treaty, granted that is a what if scenario. From the American point of view there would be no such thing and they would fight on and defeat Japan which attacked them and started the war.
