Russia holds a 97–3 advantage over Belarus on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (99% of the combined total, $190bn) and economic size (GDP) (97% of the combined total, $2.2tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
