Mexico holds a 90–10 advantage over Cuba on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (99% of the combined total, $13.6bn) and economic size (GDP) (95% 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
