This deterrence logic produces a snowball effect. With Russia and the US holding 18,000 of the world’s current stockpile of 19,000 nuclear weapons, it is proving impossible to persuade any of the other nuclear-armed states to reduce their own (much smaller) arsenals until the Big Two make further drastic cuts to theirs.
这一威慑逻辑造成了雪球效应。俄罗斯和美国占了世界当前核武器存量19000枚中的18000枚，因此要说服其他有核国家削减其自身（小得多的）核武库是不可能的，除非两强进一步大规模削减核武器数量。
