This sort of arithmetic has the merit of giving some indications about burden-sharing, but it has also been shown that burden-sharing cannot be fully captured in graphs and spreadsheets. How does one decide what is a fair contribution from a country of 50 million people compared to a country with only four million?
这种算法的一个优点是可以给责任分担一些指标，但是它也显示责任分担不能用图表和数据表来完全反映。人们怎么确定一个有5千万人口的国家与一个只有4百万人口的国家相比，其贡献是公平的呢？又怎样评估提供轻型步兵部队与供应诸如直升机或空对空加油机这样的增强军力的设施的贡献的大小呢？进行这样的计算时计算的期限是多长呢？
