Verdict

Trinidad and Tobago holds a 84–16 advantage over St. Lucia on the Relative Advantage Index, a decisive margin.

The margin is driven by economic size (GDP) (91% of the combined total, $25.6bn) and active personnel (100% of the combined total, 5.0k).

2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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