Ooooh... It is gonna be a real blow when the overturning of the surrender comes down. That will be the signal for the Soviets to keep going. They are already due to launch amphibious assaults on North Korea in four days and major ground elements will likely cross the border within the next month once the supply lines catch-up.
Interesting point I didn't pick up on earlier - too busy skimming through to read the rather frequent updates.
Japan was in a pretty bad state even before the surrender became a non-surrender. How long is this news (of non-surrender and reversal of the previous surrender) going to take to get to the 'core colonies' of Korea and Taiwan? It may take more than 4 days for it to reach some quarters, even if the Soviets have already heard it, so - and this is pretty scary (and dark, as it should be!) - the Sovs could end up invading a Korea that's already been evacuated by the Japanese and end up invading, then occupying 'free' Korea.
Now how will that sit with the WAllies after the dust has settled post-war? Not going to look too good for Stalin, is it? It may even trigger an earlier Korean War to kick the Sovs out and by default a WWIII right at the end of WWII.
Hang on...! Is this where the Decisive Darkness universe is heading?
I shall sleep safe though in the full knowledge that Stalin's more than a few years away from nukes and will hopefully get curb-stomped by the WAllies. What may happen in Europe though is a completely different kettle of fish. The WAllies have drawn down even more than they had done by this point in time in OTL (and even have troops that right now, in the original DD timeline, were fighting Hitler, but are now marching into the Boso Peninsula in Chiba-ken).
This is a scary, nightmarish world that came so close to actually happening in OTL, but thankfully never did. But it's a story that must be told and is a riveting read for Korea and Japan! Keep giving me nightmares guys, I'm loving it!
