Developing Civil Society in the Non-state Sphere: Welfare and Rights-based Organisations Associated with Ethnic Armed Groups in Myanmar

Armed groups are usually seen as threats to humanitarian action but less attention has been paid where they provide assistance to constituent populations. Ethnic armed groups (EAGs) in Myanmar have developed associated welfare organisations that perform this role. This article argues this is due to EAG social embeddedness and flexibility to changes in sources of funding and support, and the influence of their relations with international humanitarian organisations. This article further contends a subset of advocacy, health and education organisations have evolved to form a nascent civil society within the political and social non-state sphere of some established EAGs.     

National security,military spending and the business cycle

This paper develops a Dynamic Stochastic General Equilibrium model where national security is an argument in the agent’s utility function and the government chooses optimally the level of military spending to maximize social welfare. National defense depends on military expenditure and on the strategic environment reflecting a potential hostile external threat. We use aggregate data on consumption, investment, and military spending for the US economy to estimate the parameters of the model. Estimation results suggest that consumption and national defense are complements and that military spending variability is mainly explained by external threat shocks although it also depends on the macroeconomic conditions. We compute impulse response functions of the main macroeconomic variables to several shocks: a total factor productivity shock, a defense technology shock, and a strategic environment shock. Surprisingly, we find that the optimal response to an increase in the external threat (a worsening in the strategic environment) will rise output by reducing consumption and increasing investment.     

What is the global landpower network and what value might it provide?

US national security guidance, as well as the US Army’s operational experiences since 2001, emphasizes the importance of working closely with partner countries to achieve US strategic objectives. The US Army has introduced the global landpower network (GLN) concept as a means to integrate, sustain and advance the Army’s considerable ongoing efforts to meet US national security guidance. This study develops the GLN concept further, and addresses three questions. What benefits can the GLN provide the Army? What are the essential components of the GLN? What options exist for implementing the GLN concept? By developing the GLN concept, the Army has the opportunity to transition the GLN from an often ad hoc and reactive set of relationships to one that the Army more self-consciously prioritizes and leverages as a resource to meet US strategic objectives.

从抗日民族统一战线的建立看中国共产党的中流砥柱作用

抗日战争是中华民族进行的一次伟大的民族解放战争。在这场为人类文明而战、为中华民族生存而战的残酷较量中,中国共产党及其领导的人民武装逐步成长为抗日民族统一战线的核心力量,成为中华民族团结抗战中坚不可摧的中流砥柱。     

INTEGRATING NUCLEAR WEAPONS STOCKPILE MANAGEMENT AND NUCLEAR ARMS CONTROL OBJECTIVES TO ENABLE SIGNIFICANT STOCKPILE REDUCTIONS

In his 2009 Prague speech and the 2010 Nuclear Posture Review, President Barack Obama committed the United States to take concrete steps toward nuclear disarmament while maintaining a safe, secure, and effective nuclear deterrent. There is an inherent tension between these two goals that is best addressed through improved integration of nuclear weapons objectives with nuclear arms control objectives. This article reviews historical examples of the interaction between the two sets of objectives, develops a framework for analyzing opportunities for future integration, and suggests specific ideas that could benefit the nuclear weapons enterprise as it undergoes transformation and that could make the future enterprise compatible with a variety of arms control futures.     

Modelling the demand for national security expenditure: a note

In the past, national security for the majority of countries was almost exclusively associated with an external military threat emanating from a rival state(s). This was reflected in the standard models for the demand for military expenditure. The emergence of new security challenges such as terrorism, transnational crime networks, failed and rogue states, has profoundly affected the international security environment and the concept of national security. This note develops a model for the demand for national security expenditure adopting a broader, more inclusive definition of national security and includes concomitant budgetary outlets to meet the new security challenges.     

THE EXERCISE OF NATIONAL SOVEREIGNTY

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.
