卡耐基学者建议美政府从限制中国核武器新发展下手

美防务新闻3月12日讯

美国卡耐基国际和平基金会学者普拉纳·瓦迪和安吉特·潘达发文称,就中国的核武器而言,仅谈论数量问题根本“不叫事儿”,应该通过军控谈判和条约来限制中国发展新的核力量。针对美国参议员汤姆·克顿与美军印太司令部司令菲利普·戴维森的对话,文章称,谈中国“核威胁”,应该从精准把握本质出发,而不是仅仅谈论数量增大问题,中美核竞争与美俄过去和现在的核竞争有本质的区别。文章列举了美国核武库现有5800枚核弹头,其中3800枚可随时部署,约1400枚处于可发射攻击状态,还有150~200枚空投式核弹在地下武库中储存。文章认为,在印太地区应该实施“以两手对两手”战略,大力发展先进的常规威慑力量,这也是美国国会设立太平洋威慑倡议支持的。


When it comes to China’s nuclear weapons, numbers aren’t everything

Threat inflation tends to lead to poor policy outcomes. When it comes to China’s nuclear arsenal, it’s important for American leaders to accurately understand the nature of the problem. Nuclear risks between the United States and China manifest differently than those of the past U.S.-Soviet nuclear competition, or that of the United States and Russia today.

Concerns regarding nuclear use in the U.S.-China context stem from, among other things, mutual mistrust and the manipulation of risk below the nuclear threshold, largely from qualitative force posture and strategy choices each country has made. Quantitative factors — most importantly the size of China’s nuclear arsenal — are less pressing.

Despite this reality, a recent exchange between Sen. Tom Cotton, R-Ark., and Adm. Philip Davidson, commander of U.S. Indo-Pacific Command, reveals how the nature of nuclear risk with China continues to be mischaracterized in Washington. Cotton expressed concern during a Senate hearing that China may attain “nuclear overmatch” against the United States if it were to triple or quadruple its nuclear stockpile. Adm. Davidson agreed.

But Cotton misstated the degree to which China may expand its nuclear warhead stockpile relative to the United States. In doing so, he suggests the United States should focus more on quantitative nuclear arms racing, stating that “it is much better to win an arms race than to lose a war.”

Cotton’s framing gets several facts wrong. First, the U.S. Defense Department’s most recent report on the Chinese military states that China’s warhead stockpile is “currently estimated to be in the low-200s.” This pales in comparison to the total U.S. inventory of 5,800 nuclear warheads.

Of these, 3,800 are available for deployment, with approximately 1,400 warheads already on alert delivery systems. Additionally, 150-200 gravity bombs sit in protected bunkers at five European air bases. Insofar as “overmatch” — a concept with little use to nuclear strategists — exists, it is squarely with the United States.

Cotton also incorrectly suggests that the U.S.-Russia New START arms control pact limits the United States to “800 deployed nuclear weapons.” In reality, New START permits 1,550 deployed warheads (including bombers counted as a single warhead apiece per treaty rules).

So why are senior officials and members of Congress so focused on numerical comparisons? Examining qualitative differences between U.S. and Chinese nuclear forces and accompanying doctrines is harder to do. These differences tell a slightly less alarmist story when it comes to the bilateral nuclear competition, but by no means present easy answers to the project of deterring China or avoiding nuclear war.
