Thanks for the feedback guys.
Japan will have lost 11 IPCs from DEI in the next 2 turns (no stopping it now), and are currently on 35 (give or take). I think the biggest mistake made by the Axis was giving up on Cairo early. He held back his attack which gave me a chance to build a minor IC there (a must for the UK I think), and effectively destroying Italy as an attacking force within 8 turns. I did however commit the vast majority of the UK London resources (and all UK Pacific Navy forces) in taking Africa and the Middle East as there are plenty of IPC to grab. It also facilities easy transfer of resources to aid the UK Pacific. On the flipside Germany was able to roll Russia (probably 2-3 turns too early due to my tactical error). At this point the panic set in as I thought I had thrown away a good winning lead (not that I care that much about losing but I hate making mistakes as I feel it dishonours my adversary). Hence I decided to put the foot down on Japan and spent 65 IPC on navy and air units to knock out the Japanese fleet at the Philippines which will lead to the total capture of the DEI in the next two turns. I figure that now I have economic superiority overall, that it is just a matter of time for an Allied victory. Surely the Germans cannot last long with so many fronts opened up and two severely weakened allies. Rome and France are vulnerable should I choose to push hard.
I also take onboard the feedback that not building a minor IC by the Japanese on the DEI islands was a mistake. He did built one in the captured Philippines but far too late to be effective. Admittedly he had one absolutely catastrophic roll when trying to take Burma with a superior force which was a real show stopper.
Win or lose I think that AA40 Global is by far the most dynamic and interesting of all the AA editions that I have played over the past 20 years (showing my age a little).
