HEAD TO HEAD
Ukraine vs United Kingdom
Verdict
United Kingdom holds a 63–37 advantage over Ukraine on the Relative Advantage Index, a clear margin.
The margin is driven by economic size (GDP) (95% of the combined total, $3.7tn) and military spending (51% of the combined total, $89.0bn). Ukraine 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
