"What he did not have was the transportation means to move them all into Bataan once WPOIII had again put into effect."

There is a key point. With insuffcient supplys in Battan & too little transport MacArthur needed to stall the Japanese landings to preserve his supply base. Unfortunately the Japanese struck before the US/PI army could be deployed for effective defense of the landing sites.

Had somehow a US/PI army survived, preserving air bases into the summer of 1942 then the naval & air battles that revolved around New Guniea & the Solomons would have started sooner & extended to the Phillipines.

This would be interesting variant for a stratigic level wargame of the Pacific war.
