Question

Think about u.s participation in the war in Europe. How might the axis have benefited by gaining control of Great Britain by 1942

Answer 1

In 1942, Great Britain was at the head of the British Empire, the largest Empire in  known history.

At it's peak, the empire consisted of nearly 25% of the world's population, a large landmass, unmatched resources and hundreds of millions of subjects.

If the axis were able to control Great Britain, they would quite possibly have complete hegemony over the world.
