Italy holds a 84–16 advantage over Switzerland on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (86% of the combined total, $48.1bn) and economic size (GDP) (72% of the combined total, $2.4tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
