Indonesia holds a 69–31 advantage over Thailand on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (72% of the combined total, $15.0bn) and economic size (GDP) (73% of the combined total, $1.4tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
