'Freedom for Australia and New Zealand' is ahistorical and vaguely insulting. They weren't just functioning democracies, they were more democratic than most 'free' nations at the start of the game.
How's the free and democratic Japan supposed to be saving them exactly? 'Alright, Britain, you need to give the Australasians more constitutional flexibility. No, ignore the fact that they could achieve that by passing a law in their own parliaments, you need to unilaterally do it. That's what freedom means. If you don't, we'll attack you- and also them- so that once we've conquered their democracies, we can give them democracy. Freedom!'
