HEAD TO HEAD
Japan vs Poland
Verdict
Japan holds a 72–28 advantage over Poland on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (81% of the combined total, $4.0tn) and military spending (57% of the combined total, $62.2bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
