Spain holds a 99–1 advantage over Monaco on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (99% of the combined total, $1.7tn) and active personnel (100% of the combined total, 124.0k).
2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
