Argentina holds a 79–21 advantage over Uruguay on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (89% of the combined total, $638bn) and military spending (66% of the combined total, $3.9bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
