HEAD TO HEAD
Indonesia vs Singapore
Verdict
Indonesia holds a 71–29 advantage over Singapore on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (72% of the combined total, $1.4tn) and logistics & power projection (95% of the combined total, 198). Singapore leads on military spending.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
