Since the July 2009 Boko Haram terrorist outburst in Nigeria, there have been increasing questions on the phenomenon in the country. There has not been any substantial analysis on the emergence of the Boko Haram group and its terrorist activities in Nigeria as the out-rage continues. This study is advanced to explain the phenomenon of Boko Haram terrorism in Nigeria. It employs the levels of analysis framework popular in the field of international relations to explain the terrorism at three major levels: individual, state and international. The study relies on dependable news reports, which include interviews with key actors relevant to the subject matter, and finds that Boko Haram terrorism has its roots in the ideology and motivations of its founder and members, the failures and deficiencies of the Nigerian state, and the modern trend of religious terrorism in the international system.  相似文献

The criticism of James, Solberg and Wolfson (JSW) (1999) by Oneal and Russett (OR) is not responsive to the methodologica] issues at stake. JSW argued that war is an endogenous feature of the world political and economic system. If its causes are to be measured, it must be as a structural equation in a simultaneous system. Wedded to the idea that “democracies never fight each other,” OR rely on a single equation to justify their view. JSW claim that such an equation may be an ad hoc reduced form with no causal implications unless the equation is explicitly identified as a structural equation. JSW expand the model to explain democracy and conflict as two endogenous variables. JSW do not claim to have discovered the true relationships between these variables by their minimal expansion of the structural relation. They do show that unless these (and other) variables are treated as part of a system, the results are unstable, contradictory, of minimal size and not a reliable guide to public policy.  相似文献

Skeptics of the Bush administration have castigated its strong aversion to formal international agreements in responding to the threat of the proliferation of weapons of mass destruction (WMD), citing unilateral actions as the default alternative. Yet this critique misses the growing emergence of a conscious framework guiding the administration's actions: an emphasis on the exercise of national sovereignty and the corollary principle of sovereign responsibility. Rejecting the paradigm of arms control as the answer to WMD proliferation, the current administration instead advocates a toolkit of alternative mechanisms based on the full exercise by individual nation, states of their domestic authorities and rights under international law, acting in their capacities as responsible citizens of the global community. This paper will examine that philosophical approach and its concrete application through the following policies: (1) the Proliferation Security Initiative; (2) enforcement of national laws and regulations as exemplified by United Nations Security Council Resolution 1540 and the U.S. proposals for consideration by Biological Weapons Convention signatories; and (3) preemptive warfare to disarm the WMD programs of a threatening state.  相似文献

This article seeks to assess the magnitude of military reform in Indonesia and its impact in establishing greater levels of professionalism within the armed forces. To this end, the authors will offer some reflections on the studies of civil-military relations and military transformation for inculcating a higher degree of military professionalism; analyse to what extent the process of military reform in Indonesia has reshaped the institutional role of the armed forces; and discern three major strategic gaps in Indonesia's military reform, namely the “legal loopholes and regulation vacuum,” the “shortcomings of democratic civilian control,” and the “defence-economic gap.” This article asserts that military professionalism will grow more substantially depending on the ability of civilian elites to exercise effective control over the military and the capacity of the government to transform the military establishment keeping pace with strategic challenges and operational requirements.  相似文献

为发挥鱼雷的作战效能,提出潜射鱼雷有利相遇态势的概念,指出当一次转角射击不能满足鱼雷以有利相遇态势接近并发现目标时,各种自导方式的鱼雷均需要二次转角射击。在给出二次转角射击时机、解算模型的基础上,着重对预定相遇态势射击的关键----二次转向点的选择问题进行了系统研究,引入基于鱼雷自导探测距离的二次转向点与预定相遇点之间距离的选择方法,使得二次转向点的选择更具合理性和针对性,且适用于包括直航鱼雷在内的各种鱼雷。  相似文献
