Africa and the 2015 NPT Review Conference

African states' attendance at and participation in the preparations for the 2015 Review Conference of the Parties to the Treaty on the Non-proliferation of Nuclear Weapons (NPT) has produced mixed results, with the continent acting as both agent and bystander in respect of certain issues. African agency is evident in, for example, its position as a member of groupings on Iran's nuclear weapons programme and the Middle East Nuclear Weapons Free Zone. Less agency is evident in states' individual actions. This underscores the importance of African states' preference for multilateralism. However, African agency is also less evident in African multilateral efforts at the NPT preparatory meetings. The impact of these developments on the 2015 NPT Review Conference is too soon to tell but may bode ill for African agency.     

Kazakhstan's Nuclear Decision Making, 1991–92

This article examines Kazakhstani nuclear decision making from December 1991 to May 1992. The study is based on unique archival data and reveals how Kazakhstan's policy makers solved a nuclear dilemma that the nation faced in its first years of independence. The article reconstructs the internal policy-making process behind the decision made by President Nursultan Nazarbayev and his circle of advisors to accept non-nuclear status. The author argues that Almaty elaborated a deliberately ambivalent strategy toward the republic's nuclear status with the aim of maximizing the state's strategic interests. The article reviews external pressures affecting Nazarbayev's course of action and discusses policy options articulated during this period.

New terrorist threat to India's internal security: the danger from Pakistan's “Karachi Project”

The spectacular commando-style terrorist strike on Mumbai in November 2008 exposed India's lax internal security structure. As nearly all the security apparatus broke down during the long spell of attacks, massive public outrage flared up across the country calling for a firmer government response. Shockingly, India has done little to prevent a recurrence and a new security threat faces the country every single day not merely before but even after the Mumbai attacks. In contrast, Pakistan's Inter Services Intelligence and the Lashkar-e-Taiba have successfully evaded pressures from both India and the international community and continue their terror campaign against India under the “Karachi Project” with the explicit intention to unsettle South Asia. Classified documents indicated that India is at the forefront of a cataclysmic “nuclear terrorism” threat from a “combination of Pakistan-based terrorists and homegrown radicals.” This article analyses the danger posed by the Indo-Pak radical groups targeting India and India's lack of preparedness to the new security threat from the “Karachi Project.”
