Verdict

United Kingdom holds a 61–39 advantage over South Korea on the Relative Advantage Index, a clear margin.

The margin is driven by military spending (65% of the combined total, $89.0bn) and economic size (GDP) (66% of the combined total, $3.7tn). South Korea leads on active personnel.

1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
