All well and good - though I haven’t been as lucky. And from reading these forums, many others haven’t either. But again, those are all in the context of AAP40 and not Global. Not having had the benefit of playing a Global game yet, I can’t really say for sure whether the US Korean IC would even become a consistent strategy.
In any event, I was only pointing it out as a perhaps unforseen consequence of Russian expansion - one that could wind up being in Japan’s favor.
