As others have said, the UK & US have to do enough to keep J busy. Especially given the role it can play in helping G in capturing Moscow. Stalingrad is not that far from J’s opening territories, with China easy meat.
But that has to be achieved while focusing as much resource as possible in reinforcements to Moscow, denying Africa to G, getting an allied fleet off the coast of Europe and perhaps SBRs on Berlin.
Balancing all these demands for limited resources is part of what makes it a great game!
A warm welcome to the forum mosuper :-)
