Mexico holds a 98–2 advantage over Belize on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (100% of the combined total, $13.6bn) and economic size (GDP) (100% of the combined total, $1.9tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
