 From this point onward, the strategy of the Allies, other than the USSR, is better addressed as joint Allied Strategy

In the December 1941, at the Arcadia Conference, the Allied leaders agreed to the "Germany first" principle whereby Germany was to be defeated first, and then Japan.However, Allied land forces would not be capable of invading the mainland of Europe for years, even as Joseph Stalin pressed for the western allies to alleviate pressure on the Eastern front.Supporting the Soviet war effort was a significant element of Allied strategy, and significant aid was shipped to the USSR through the Lend-Lease programme.
