Nuclear deterrence and cyber warfare: coexistence or competition?

Nuclear deterrence and cyber war seem almost antithetical in their respective intellectual pedigrees. Nuclear weapons are unique in their ability to create mass destruction in a short time. Information or “cyber” weapons, at least for the most part, aim at sowing confusion or mass disruption instead of widespread physical destruction. Nevertheless, there are some intersections between cyber and nuclear matters, and these have the potential to become troublesome for the future of nuclear deterrence. For example, cyber attacks might complicate the management of a nuclear crisis. As well, information attacks on command-control and communications systems might lead to a mistaken nuclear launch based on false warnings, to erroneous interpretations of data or to panic on account of feared information blackout. It is not inconceivable that future nuclear strike planning will include a preliminary wave of cyber strikes or at least a more protracted “preparation of the battlefield” by roaming through enemy networks to plant malware or map vulnerabilities.     

Reconsidering minimum deterrence in South Asia: Indian responses to Pakistan’s tactical nuclear weapons

India’s nuclear doctrine and posture has traditionally been shaped by minimum deterrence logic. This logic includes assumptions that possession of only a small retaliatory nuclear force generates sufficient deterrent effect against adversaries, and accordingly that development of limited nuclear warfighting concepts and platforms are unnecessary for national security. The recent emergence of Pakistan’s Nasr tactical nuclear missile platform has generated pressures on Indian minimum deterrence. This article analyzes Indian official and strategic elite responses to the Nasr challenge, including policy recommendations and attendant implications. It argues that India should continue to adhere to minimum deterrence, which serves as the most appropriate concept for Indian nuclear policy and best supports broader foreign and security policy objectives. However, the form through which Indian minimum deterrence is delivered must be rethought in light of this new stage of regional nuclear competition.     

Open source intelligence (OSINT) for conflict monitoring in contemporary South Africa: Challenges and opportunities in a big data context

This article argues that aspirations of maintaining a dominant influence over sub-Saharan security issues has spurred the French and British leadership of European Union (EU) foreign and security policy integration, just as it has informed military capability expansions by the armed forces of the main EU powers. While Europe's initial African focus was on stabilising a continent marred by state failure, civil wars and genocides, changes in the global security context, especially the shift towards multipolarity manifest in China's growing engagement, has prompted a complementary focus on deterring other powers from making military inroads into the subcontinent. Hence Europe's sub-Saharan security focus is shifting from stabilisation towards deterrence. This helps explain recent military procurements which, in spite of the extremely challenging fiscal position of most EU member states, feature large-scale investments in long-range deterrence capabilities.     

NO SUCH THING AS A FREE LUNCH

The funding of international nuclear risk mitigation is ad hoc, voluntary, and unpredictable, offering no transparent explanation of who is financially responsible for the task or why. Among many non-nuclear-armed states, this exacerbates a sense of injustice surrounding what they see as a discriminatory nuclear regime. The resulting erosion of the regime's legitimacy undermines support for efforts to prevent nuclear weapons dissemination and terrorism. This article proposes a transparent, equitable “nuclear-user-pays” system as a logical means of reversing this trend. This system envisions states contributing financially to international efforts to mitigate nuclear risks at a level relative to the degree of nuclear risks created by each state. “National nuclear risk factors” would be calculated by tabulating the risks associated with each state's civilian and military nuclear activities, as well as advanced dual-use and nuclear-capable missile activities, multiplying the severity of each risk by the probability of it occurring, and combining these results. A nuclear-user-pays model would create financial incentives for national and corporate nuclear risk mitigation, boost legitimacy and support for nuclear control efforts among non-nuclear-armed states, assist in preventing nuclear weapons dissemination and terrorism, and advance nuclear disarmament by helping progressively devalue nuclear weapons.

NUCLEAR POWER IN THE MIDDLE EAST:

With the exception of Iran, no Middle Eastern state has an operating nuclear power reactor. Several states, including the United Arab Emirates, Saudi Arabia, Qatar, Kuwait, Israel, Syria, Jordan, Turkey, and Egypt are considering constructing such reactors; some have even taken steps towards commencing nuclear power projects. There exist, however, considerable economic, technical, safety, and security challenges to achieving these goals, many of which are acute in the Middle East region. Regional and international cooperation on nuclear technology could not only help regional states meet their energy objectives, but it could also help to build trust among states as a basic step towards a future Middle East Weapons of Mass Destruction-Free Zone.     

U.S.–RUSSIAN NUCLEAR COOPERATION AND THE CTBT

Post-Cold War “lab-to-lab” collaborations on unclassified scientific issues between U.S. and Russian nuclear weapons laboratories set the stage for bilateral cooperation in materials control and other nuclear areas. They also became the major element in a cooperative process initiated by a Presidential Decision Directive to ensure Russia's compliance with the Comprehensive Nuclear-Test-Ban Treaty. These collaborations have always been highly favored by leaders of the Russian nuclear weapons complex—the same leaders who oversee Russia's participation in various government-to-government programs. This article reviews these collaborations and examines the possibility that U.S. rebuffs of Russian proposals and the U.S. failure to keep promises of expanded collaboration could contribute to Russia's reluctance in major programs and even lead to a return to nuclear testing by Russia. The author argues that a renewed U.S. commitment to the process should be an immediate goal of the Obama administration and is an essential step in re-engaging Russia to solve the nuclear problems remaining from the Cold War. Steps for doing so are recommended.     

The 1983 Nuclear Crisis – Lessons for Deterrence Theory and Practice

This article distills insights for the scholarship of deterrence by examining the 1983 nuclear crisis – the moment of maximum danger of the late Cold War. Important contributions notwithstanding, our understanding of this episode still has caveats, and a significant pool of theoretical lessons for strategic studies remain to be learned. Utilizing newly available sources, this article suggests an alternative interpretation of Soviet and US conduct. It argues that the then US deterrence strategy almost produced Soviet nuclear overreaction by nearly turning a NATO exercise into a prelude to a preventive Soviet attack. Building on historical findings, this article offers insights about a mechanism for deterrence effectiveness evaluation, recommends establishing a structure responsible for this endeavor, and introduces a new theoretical term to the strategic studies lexicon – a ‘culminating point of deterrence’.
