To Go Nuclear or Not: Does the Non-Proliferation Treaty Really Matter?

"For many, the NPT is the foundation of nuclear order. Actually, the NPT is much less influential in international security than is commonly believed."

The nuclear status quo of the world is in flux. The rise of China and the growing Russian challenge have implications for proliferation incentives. This poses an extraordinary challenge to the nuclear order, which is codified by the Non-Proliferation Treaty (NPT), a fundamentally status quo–oriented treaty. The 2015 Review Conference takes place in New York next year. For many, the NPT is the foundation of nuclear order. Actually, the NPT is much less influential in international security than is commonly believed. The decision by countries of whether or not to go nuclear is first and foremost about strategy and geopolitics given a state’s specific position in contingent historical situations. The focus in current debates on “strengthening” the NPT and the nonproliferation regime to assure non-nuclear states that they are safer without nuclear weapons per se misses the point. Rather, it is a feeling of long-term security that diminishes the incentives for states to go nuclear. Signing the NPT may have a certain value in making states feel safer, but it is not the central factor.

One should not fall victim to a nonproliferation-centered perspective. This perspective is alarmist by tendency. It attributes highest value to the NPT regarding individual nonproliferation choices. But it puts the superior politico-strategic perspective into brackets, which has greater influence on individual proliferation choices than often assumed. In a stimulating essay, Elbridge Colby argued that the United States should favor geopolitical considerations over the goal of nonproliferation in its alliance policies. Alliances may be regarded as nonproliferation tools. But first of all, they should be seen as geopolitical tools that will not necessarily “prevent” proliferation. Additionally, new research on nuclear history has shown that the United States is far from having a consistent nonproliferation track record. Nonproliferation policy was not an end in itself, but rather one of many competing foreign-policy interests.

Our own research on West Germany and Australia during the Cold War confirms that the NPT had no effect on Bonn and Canberra’s decision whether or not to go nuclear. Additionally, our research shows that U.S. alliances should primarily be regarded as political instruments to maintain U.S. interests and the U.S. power position in geopolitical terms.

In the case of West Germany, the NPT had in fact no nonproliferation effect. Even if the Federal Republic of Germany’s (FRG) accession to the treaty (signing 1969, ratification 1975) cemented the non-nuclear status of the FRG, the NPT was not a necessary or sufficient tool to keep Germany non-nuclear. Given the persistence of the Cold War, the division of Germany, the FRG’s undisputed Westbindung and the national interest to achieve reunification, there was no “danger” that the FRG would go nuclear sooner or later without the NPT. Bonn had constantly pursued a limited nuclear revisionism since the late 1950s when West Germany had started to develop a peculiar form of nuclear policy that was oriented towards NATO and the U.S. nuclear umbrella. In Bonn, any assessment of costs (like a potential loss of protection in NATO and a military intervention at least by the Soviet Union) and gains let the policy option to strive for a national nuclear capability look totally unbearable. The German government even shared a basic thesis of nonproliferation policy: the spread of nuclear weapons would be destabilizing. The German government was in favor of nonproliferation policy. But it did not accept any means to deal with the prospect of proliferation. It rejected the NPT as a means of power politics to consolidate the relative “margin of power” of the nuclear beati possidentes. Originally, the German government rejected the NPT for a couple of other complex reasons, but not because of an interest in becoming an atomic power. According to Germany’s limited nuclear revisionism, Bonn envisaged to bolster the FRG’s position in NATO as a nuclear alliance and to expand Bonn’s influence in nuclear matters without becoming an atomic power. The overall function of German nuclear policy was deeply political. By pursuing a limited nuclear revisionism, West Germany intended to fortify her ties to the West. Thus, Bonn’s nuclear policy ultimately had a geopolitical function. Consequently and regarding West Germany during the Cold War, U.S. extended nuclear deterrence and NATO can be regarded as geopolitical tools and not as positive security assurances, which decisively incentivized Bonn not to seek the national control of nuclear weapons.
