Totally agree. Without the need to suck up to the Americans to get forces to defend Australia, ( I could have phrased that more diplomatically but i chose not to), as in OTL, and the more successful Commonwealth response to the Japanese onslaught, Curtin would not be so dismissive of British support and surrendered Australian control over the Local area to Mac Arthur. And of course ITTL Churchill's desire to decide where Australian Divisions would be sent, against the wishes of their own Government, are not so controversial. Well, yes they would be, but not as much. Without Burma being threatened, the desire to divert them to Rangoon would not happen. And with Singapore holding, then the desire to bring them home to Australia will not be as great, So sending them to Singapore is a good result.
So what can Dugout Doug expect when he is told to leave Bataan, due to the pressure on FDR by MacArthur's supporters?
Australia is not the fall back position of OTL. It is still a rather backwater area, rather than the springboard for an eventual allied advance back to the Philippines.. The main action is taking place in Malaya and Borneo and DEI. Hardly areas the USA want to intrude into. National sovereignty and all that! So what advantage does having Dugout Doug provide? Where can he be sent? The Solomons is not yet a vital area and may not even get to that point. In any case, as a place surrounded by water with many islands, it is more likely to be a Navy command. The Philippines is an American problem so the Americans will need to work out how to regain. The question is how? And with what forces? The rest of the Allies are fighting their own battles. The USA will have to figure out how to take back the Philippines on their own. After all, if the Commonwealth and the Dutch can successfully defend their own territory or at least hold the Japanese from advancing too far, surely it be expected that the mighty USA, under such a great general as Dougout Doug can reclaim the Philippines in the next 12 months.
PNG is not yet a problem area. Japanese forces are being drawn to Malaya/DEI like bees to honey. It is not inconceivable that the many SNLF will be redirected to the DEI. So no real threat down the Solomons Island Chain. In fact, why would they? The main threat to Japanese war aims is in Malaya and DEI. Cutting off American supply lines to Australia does not help the immediate problem.
And what aid does America have available to send to Australia? A few NG Divisions and some fighter Sdns. And how long before they are deployed into Java?
So what does Dougout Doug arrive in Australia (presuming that is where he is evacuated to!) to find? Bugger all!
And if he is evacuated to Singapore or Java, well, what can he offer? Command, eventually, of a few undertrained and ill equipped NG Divisions, vs the numerous battle hardened and successful Commonwealth Divisions and Corps, run by people who have been doing this job since 1939? The Bataan gang would find themselves well out of their depth. And to Dougout Doug's disgust, he would find himself merely a small frog in a big pond. (yes, frog! Croaking all the way!) Nervous breakdown as everyone ignores his proclamations from the Mount, anyone?
