This study analyses an arms race between South and North Korea over the period 1963–2000. Despite the strategic importance of the Korean Peninsula, the arms race between South and North Korea has rarely been studied. In this study, the South–North arms race is empirically estimated using Richardson’s action–reaction model. The pattern of South–North arms race between the Cold War (1963–1989) and the post‐Cold War eras (1990–2000) as well as the existence of an arms race is examined comparing both countries’ defence spending, number of military personnel and tactical aircraft.  相似文献

We address empirically the question of why international economic sanctions are, or are not, chosen as instruments of foreign policy and the question of what determines their success. We hypothesize that cultural linkages between nations are an important factor in explaining both instrument choice and conflict outcomes. Countries that share significant cultural attributes are found to be less likely to apply economic sanctions against one another than countries lacking such cultural ties. However, it is precisely in the case of culturally similar sender and target nations that sanctions are most likely to succeed.  相似文献

Using an event study approach to analyze stock market data from the United States, I investigate how regulations on conflict minerals sourced in the Democratic Republic of the Congo were perceived by investors. I find that for a subset of mining companies, stock returns were abnormally high when regulations in the US became more likely. I also find that returns were higher for communications equipment manufacturing companies when strong regulations in the DRC were announced. I argue that these responses were due to the competitive environments faced by each of these company types. These findings relate to debates surrounding the effects of the conflict mineral regulations. While some critics argue that reporting requirements were tantamount to a ban on minerals from the DRC, I find that stock returns for a subset of companies were sensitive to legislation in the DRC after legislation became law in the US, suggesting that market participants did not expect a complete trade ban on regulated mining and trading activities.  相似文献

TANZANIA     
Protracted state collapse in Somalia has led to a multiplication and diversification of armed groups. We can speak of at least five types of armed group: faction, warlord, business, court, and Islamic militias. These groups differ in important ways, yet often are simply classified as ‘militia’ or ‘warlord’. This essay seeks to add a measure of analytical rigour to the classification of armed groups and provides a comparison using a framework of purpose, motivations, logistics, and command, control and communication. It concludes with some observations about the importance of making these distinctions when formulating policy for this region.  相似文献

The economic value, social status and symbolic meaning of small arms are particular and temporal in nature. This is demonstra ted through a historical account of the dynamics of cultural change and adaptation in Nuer society. Specifically, the article shows how attitudes towards small arms shif ted over time from a positive valuation of guns as prestigious objects, to ambivalence between the need for protection and the experience of increased local lawlessness and violence. More generally, it demonstrates how weapon-rela ted activities can only be fully understood when seen against a specific cultural background. Even if the display, use and circulation of weapons appear to carry cross-cultural references, typically as expressions of power and masculine identity, the meaning is always primarily local. Therefore, strategies to reduce the destructive impact of small arms through demand side programs, based on voluntary participation, can only be carried out successfully if built on an in-depth understanding of a particular cultural context.  相似文献

NEW TERRORISM     
New or contemporary international terrorism associated with Islamic fundamentalism and the struggle against Zionism and American interests is a recent phenomenon in Kenya, different to that experienced during the struggle against colonialism. Many explanations have been offered as to why Kenya is being targeted, but have not sufficiently explored its close relationship with the West—especially Britain and the United States, the perceived connection between Israel and the former Presidency of Daniel Arap Moi, domestic forces and government policy. Externally the most important explanations for the increase in regional terrorism are the three waves of global terrorism since 1967, the most recent and significant of which is associated with Osama bin Laden and the Palestinian Intifada. These events reverberated in the region, Sudan and Somalia in particular, but also internally. Both internal and external attribution factors explain the resurgence of new terrorism in Africa. In the case of Kenya, terrorist attacks are associated with the country's internal domestic processes and a naïve approach to broader international issues.  相似文献

The Arab Spring, a pro-democracy uprising that has been sweeping through North Africa and the entire Arab world since 2010, has been described as a cataclysmic revolutionary wave that has left the overthrow of political regimes in its wake. Studies have comprehensively x-rayed the political and socio-economic circumstances that gave rise to the uprising. Apart from the impact of the uprising on political developments and democratic governance in the Arab world in particular and the world in general, the circumstances that resulted in the revolutions constitute empirical security implications for Nigeria. This is the focus of this article. Using the Ibrahim Index of African Governance (IIAG) and other selected indicators, this article draws a comparative analysis of the key factors that led to the uprisings in Egypt, Libya and Tunisia, pointing out areas of social and security tensions in Nigeria. Based on these findings, it points out the urgency of and imperative for security sector reforms in Nigeria.  相似文献

This article assesses the prospects for a strategy of incrementalism to lead to achievement of the core bargain of the Treaty on the Non-Proliferation of Nuclear Weapons: non-nuclear weapon states' nuclear nonproliferation in exchange for nuclear weapon states' nuclear disarmament to the point of “global zero.” Game theory, prospect theory, and liberal international theory are used to evaluate the potential of a strategy of incrementalism. While separately each has insights to offer, it is when all three theoretical approaches are used in tandem that meaningful explanatory gains emerge. The article concludes that incrementalism probably cannot lead to complete nonproliferation and global nuclear zero. Instead, signal events (as described by prospect theory) are needed to “punctuate” incremental processes in negotiations (best explained by liberal international theory) in order to move past hindrances such as international structural constraints (exemplified by game theory) and the conservative risk-taking propensities of state elites (described by prospect theory).  相似文献
