El Salvador holds a 70–30 advantage over Nicaragua on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (81% of the combined total, $490m) and economic size (GDP) (64% of the combined total, $35.4bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
