Ethiopia holds a 80–20 advantage over Eritrea on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (99% of the combined total, $150bn) and military spending (74% of the combined total, $528m).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
