Comparing Germany with Britain alone gives a different picture from comparing it with the whole British Empire. Both sets of figures can be technically correct while answering different questions about war potential. Japan expected a conflict that involved the empire's wider resources. German hopes that parts such as Canada or Australia would stand aside underestimated that support in this interpretation. Industrial comparisons therefore need to count the participants expected to sustain the actual war.
