HEAD TO HEAD
India vs Iran
Verdict
India holds a 82–18 advantage over Iran on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (93% of the combined total, $92.1bn) and economic size (GDP) (89% of the combined total, $3.9tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
