Spain holds a 67–33 advantage over Thailand on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (87% of the combined total, $40.2bn) and economic size (GDP) (77% of the combined total, $1.7tn). Thailand leads on active personnel.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
