Iran holds a 93–7 advantage over Afghanistan on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (96% of the combined total, $7.4bn) and economic size (GDP) (97% of the combined total, $475bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
