HEAD TO HEAD
Bahrain vs Iran
Verdict
Iran holds a 90–10 advantage over Bahrain on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (83% of the combined total, $7.4bn) and economic size (GDP) (91% 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
