HEAD TO HEAD
Canada vs United Kingdom
Verdict
United Kingdom holds a 61–39 advantage over Canada on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (70% of the combined total, $89.0bn) and economic size (GDP) (62% of the combined total, $3.7tn). Canada leads on logistics & power projection.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
