In @fester 's alternate timeline I think it's clear there will not be a Guadalcanal and Solomons campaign. Nor will there be the heavy fighting of the Kokoda Track and the Papua New Guinea campaign. And I don't think Rabaul is going to have the importance it did in OTL. The high water line of the Japanese Empire's violent expansion is occuring in Malaya and in Southern Indonesia on the islands of Java and Timor. Those places will be similar to the Guadalcanal and the New Guinea battles of OTL. A bloody attritional fight with both sides committing as many units as are available and can be spared from other areas. How long will the ATL battles of Timor and Java continue before the Allies achieve victory or possibly there is instead a pyrrhic victory for a depleted and crippled Japanese military? Who then will not be able to conduct any further offensive actions but will instead be forced to prepare for the Allied build up and counter offensive. While being in a much poorer strategic position in this TL. I'm very much looking forward to the next updates in fester's excellent and convincing story.
