Saudi Arabia leads on military spending (64% of the combined total, $83.2bn) and logistics & power projection (57% of the combined total, 50), which South Korea 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
