Success and Failure in Terrorist Investigations: Research and Lessons from Northern Ireland

Police investigations of terrorist incidents are rarely straightforward. This paper reports the findings of research that looked at low-level paramilitary attacks in Northern Ireland which have taken place during the ceasefire era. Of 500 incidents studied, 28 were followed by the arrest of suspects. The study examines what factors were important for linking later arrests with other features of the incident. These results are discussed in terms of the wider implications for the successful investigation of paramilitary offences and in terms of the specific implications for investigative policing within Northern Ireland.     

Security,autonomy and defense burdens: The effects of alliance membership in the 19th and 20th centuries

This paper investigates the effect of alliance membership on the defense burdens of major powers in the 19th and 20th centuries. We hypothesize that the reactions of states to alliance membership will be different in the pre‐nuclear and nuclear eras. Possession of nuclear weapons by allies makes the security provided by the alliance more akin to a collective good than is the case in the pre‐nuclear era. States join alliances for two reasons: security and autonomy. The effects of each of these concerns are identified. We include in our model such alliance‐level factors as the power equivalence of the allies and the number of states in the alliance. We also look at state‐level variables such as power position within the alliance. We conclude that the nuclear period generally operates as the free‐rider principle would posit, while models based on “complementarity of effort” are more applicable in the earlier period.     

Defense spending and the macroeconomy

Given Kinsella's (1990, 1991) appeal for analysis to be pursued using sub‐annual level of data, we pursue such an endeavor in this paper. We examime the effect of defence spending on real output, the unemployment rate, price level, and interest rate covering a quarterly time frame 1960:1 to 1988:1 using an unrestricted vector autoregression framework. Our results parallel the findings of Kinsella in that there appears no causal relationship in either direction between defence spending and economic performance.     

Arms Control,Proliferation and Terrorism: The Bush Administration's Post-September 11 Security Strategy

The current Bush Administration considers ‘outlaw regimes’ and their terrorist clients acquiring weapons of mass destruction (WMD) the gravest danger to international security. Thus, arms control, proliferation and terrorism are inextricably linked. The administration also believes that arms control and non-proliferation, as traditionally practiced, do not provide effective tools for preventing WMD spread. As evidenced in Iraq, Washington subscribes to an interventionist policy of rolling back WMD programs it considers threatening. This article examines the logic that underpins US arms control and proliferation thinking and considers the implications of US policy for relations with other states deemed to be proliferation risks.     

Chinese Theater and Strategic Missile Force Modernization and its Implications for the United States

The People's Republic of China (PRC), no longer content with its longstanding ‘minimalist’ nuclear posture and strategy, is enhancing the striking power and survivability of its theater and strategic missile forces and rethinking its nuclear doctrine in ways that may pose serious challenges for the United States. Although the modernization of Chinese nuclear and missile forces may ultimately result in greater strategic deterrence stability, this change will not come about immediately or automatically. Indeed, it is entirely possible that China's growing missile capabilities could decrease crisis stability under certain circumstances, especially in the event of a US–China conflict over Taiwan.
