United States holds a 94–6 advantage over Thailand on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (99% of the combined total, $954bn) and economic size (GDP) (98% of the combined total, $28.8tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
