Australia holds a 66–34 advantage over Vietnam on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (77% of the combined total, $35.3bn) and economic size (GDP) (79% of the combined total, $1.8tn). Vietnam 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
