Poland holds a 79–21 advantage over Czechia on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (87% of the combined total, $46.8bn) and economic size (GDP) (73% of the combined total, $918bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
