Germany holds a 71–29 advantage over Iran on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (94% of the combined total, $114bn) and economic size (GDP) (91% of the combined total, $4.7tn). Iran leads on active personnel.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
