Ghana holds a 74–26 advantage over Benin on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (70% of the combined total, $507m) and economic size (GDP) (79% of the combined total, $82.3bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
