Jamaica holds a 70–30 advantage over Haiti on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (88% of the combined total, $287m) and active personnel (86% of the combined total, 6.0k). Haiti leads on economic size (GDP).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
