HEAD TO HEAD

Belgium vs Luxembourg

Verdict

Belgium holds a 94–6 advantage over Luxembourg on the Relative Advantage Index, a decisive margin.

The margin is driven by military spending (94% of the combined total, $14.5bn) and economic size (GDP) (88% of the combined total, $671bn).

1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
