HEAD TO HEAD
Germany vs Japan
Verdict
Germany and Japan are close to evenly matched, 50–50 on the Relative Advantage Index.
Germany leads on military spending (65% of the combined total, $114bn) and economic size (GDP) (54% of the combined total, $4.7tn), which Japan offsets elsewhere.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
