HEAD TO HEAD
Samoa vs Tonga
Verdict
Tonga holds a 66–34 advantage over Samoa on the Relative Advantage Index, a clear margin.
The margin is driven by active personnel (100% of the combined total, 1.0k) and logistics & power projection (75% of the combined total, 6). Samoa leads on economic size (GDP).
2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
