@Young:
If the whole historic asspect of neutral Dutch not being realisic in this regard, than I understand.
Well, since the OOB rules themselves are unrealistic about this whole “special arrangements” thing between UK / ANZAC and the Dutch, and since what you’re proposing is fairly similar to what the OOB rules say, I don’t see any problem in your proposal from that perspective. In other words, any realism problems lie with the OOB rules themselves, not with your adaptation of them.
That being said, the OOB special arrangements thing strikes me as being one of G40’s “gaming fictions” – a mechanism that was put in for reasons of gaming practicality, but which bends history to the point where things are either oversimplified or flat-out wrong. G40’s use of pro-Allied, pro-Axis and strict neutrals is another example of that sort of gaming fiction, and so is the “Administered from London” label that treats the Belgian Congo as a British territory (which it wasn’t). That’s actually a good parallel because, if I understand your proposal correctly, you’d be treating the DEI similarly to the way the Belgian Congo is treated.
Anyway, in terms of what really happened in WWII, the DEI in 1941 were still a Dutch-ruled collection of colonial territories, and Holland as far as I know didn’t have any kind of “friends with benefits” special arrangement with the UK or ANZAC regarding the DEI. If you’d like some sort of historical justification for treating the DEI as part of the UK/Pacific income (which I think you’re calling the South East Asia Command, or SEAC, as I recall), this wouldn’t pose any problems from December 1941 onward because the Americans, the British, the Dutch and the Australians briefly did team up as a joint command called ABDACOM to try to resist the Japanese. The problem, however, would be to apply the concept retroactively all the way back to June 1940 because ABDACOM was created in the wake of (rather than in anticipation of) the Japanese attacks in the Asia/Pacific theatre. I guess the simplest solution would be assume that something similar to ABDACOM (minus the Americans) might have been set up in September 1940, after the Japanese takeover of FIC, in anticipation of a possible Japanese campaign of conquest in the Asia/Pacific theatre. Sort of a preventative defensive alliance in the Pacific between nations (UK, ANZAC and Holland) which were already allies due to the war in Europe, and perhaps a signal to Japan not to get any bright ideas in the Southwest Pacific. It’s interesting to wonder if, in real life, Japan would have considered such a move to be a provocation (probably yes) or even an implicit declaration of war (maybe not).
On a lighter note, the only way to make “ABDACOM” pronouncable if you remove the “A” that stands for “American” would be to rearrange the remaining first three letters and call your defensive alliance “BADCOM”, which sounds either intimidating or hilarious depending on your mood. :)
