@MM1940 Spicy game it seems.
As Allies I would building subs and destroyers with US and start convoying germany in the Atlantic and start going into the Med and harass italy.
In pacific as well start to convoy money islands with anzac. So let them buy subs. US there need to provide transports to take a money island.
UK in middle east needs to pump out men. Abandon India and delay their move to Persia as long as possible. DO not stand and die in India. Built mechs in persia or egypt and South Africa.
