HEAD TO HEAD
Solomon Islands vs Vanuatu
Verdict
Solomon Islands holds a 56–44 advantage over Vanuatu on the Relative Advantage Index.
The margin is driven by economic size (GDP) (59% of the combined total, $1.6bn) and logistics & power projection (53% of the combined total, 8).
3 factors — military spending, active personnel, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
