Myanmar holds a 90–10 advantage over Laos on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (100% of the combined total, $5.0bn) and economic size (GDP) (82% of the combined total, $74.1bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
