I played a game where my Japanese counterpart played this strategy upon my recommendation. It was a disaster for us, because it was just not practical for controlling Asia, at all.
IC's ???
-
Japanese IC in Novosibirsk or Kazakh. Turns a survival siege into preparing a final offensive.
UK in East Europe. Final builds if Germany holds stubbornly.
UK in West Europe. Only If Germany made the mistake of insufficient counteroffensive power ready in 1-2 turns. -
IC for Japan in the east indies is ideal IMO. 4 units per turn, basically zero threat of it being taken and right to india or africa with units makes this a great place.
