The Imperfect Peace: Explaining Paramilitary Violence in Northern Ireland

This article examines why paramilitary campaigns in Northern Ireland have continued despite the current peace process. In advancing three instrumental explanations of paramilitary violence, the author provides a useful analytical framework which shows that while organizational interpretations are dominating the public discourse, republicans and loyalists continue to use paramilitary violence as a strategic means of threat and coercion. Furthermore, even though policy implications are not discussed in detail, it will be demonstrated that the dominance of organizational imperatives has resulted in excessive leniency by the state, which - in turn - has contributed to the fragility of the peace process.     

The Nuclear Peace Fallacy: How Deterrence Can Fail

Some scholars counter-intuitively argue that the proliferation of nuclear weapons increases international security by substantially reducing the chances for inter-state armed conflict. This school of thought draws heavily on the history of the American-Soviet Cold War rivalry to inform its analysis. The security dilemmas in the contemporary Middle East and South Asia where numerous states have or want nuclear weapons, however, are profoundly different than the competition between the United States and the Soviet Union. States in the Middle East and South Asia today may see nuclear weapons as usable instruments of warfare in contrast to conventional wisdom in the West that views them as weapons of deterrence and last resort. As common sense would have it, American and Allied policy designed to stem the proliferation of nuclear weapons is prudent. American diplomatic intervention, moreover, in regional crises as a third party may be needed in the future in the Middle East and South Asia to lessen the risks of nuclear warfare. Nevertheless, American policy-makers are likely in the future to find themselves facing a nuclear-armed nation-state-or soon to be nuclear weapons-capable state-in a crisis and will have to grapple with the risks of pre-emptive or preventive military action.     

未成年人监护制度的设置与立法选择

目前,我国监护法律制度还很不完善,对未成年人监护只规定了法定监护和指定监护制度,没有规定遗嘱监护和委托监护制度;现行法律规定作为指定监护的指定机关在运作实践中遇到许多问题;立法上有关监护产生的原因和监护的变更、终止事由与程序规定均不明确。这些均需要在制定我国《民法典》时进一步加以充实与完善,以充分发挥未成年人监护制度应有的作用。

The role of women in the reconstruction and building of peace in Rwanda: Peace prospects for the Great Lakes Region

In view of the fact that women bear the heaviest burden of failed states, it is inevitable and logical that they should play a central role in designing and implementing peace-building programmes. This not only improves the quality but also the increases the chances of success and the consolidation of peace. This article uses Rwanda to highlight how women are affected by collapsing states and prescribes the role that they can play in reconstructing societies emerging from violent conflicts. It strongly recommends the inclusion of women in post-conflict reconstruction and peace-building as model for good governance.

Ex-combatants Working for Peace and the Lebanese Civil Society: A Case Study in Non-communal Reintegration

Abstract

This article investigates the factors that made few Lebanese ex-combatants, who fought each other during the Lebanese civil war of 1975 and who believed they were fighting for a just cause, able to work together to establish the Fighters for Peace (FFP) association to preach peace and peaceful coexistence. It demonstrates that ex-combatants, who are cause-oriented individuals, can overcome their differences and hatred towards each other and work together for the purpose of civil peace. This can happen, if ex-combatants gradually reintegrate back into society following a two-phase model proposed by the authors.

从建设和平的视角看联合匡维和行动的困境

联合国维和行动目前面临着日益严峻的困难和挑战。其中的一个重要原因在于维和人员被赋予了过多的建设和平的职责,使得维和行动处于两难的境地。要缓解这一困境,国际社会需重新审视和定义维和行动的职责范围,大力加强和平委员会的能力建设,并给予更多的授权。在实现这些长期目标之前,维和特派团将继续代替建和委履行建设和平协调员的职责。
