France holds a 92–8 advantage over Ireland on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (98% of the combined total, $68.0bn) and economic size (GDP) (84% of the combined total, $3.2tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
