Verdict

Papua New Guinea holds a 93–7 advantage over Solomon Islands on the Relative Advantage Index, a decisive margin.

The margin is driven by economic size (GDP) (95% of the combined total, $31.8bn) and active personnel (100% of the combined total, 4.0k).

2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
