@windowwasher It would be difficult to get over there until later in the game. Take Italian Somalialand to deny them a landing spot. In other versions of the game its good to get Japanese bombers into Germany territory but in Global the italian air is more useful as a canopener.
It’d be easier for the Allies to do what you’re talking about. In the pacific, some anzac air can ride with usa, they could add a bomber and subs. UK air that survives ME battles heads east and sets up with other surviving units. If the BB lives, it can join that stuff, or head to queensland to protect that… By keeping some units from UK and ANZAC, the USA could mount an offensive/defensive battle to the last guy–the other 2 allies come in and finish off any Japanese units that live.
