Diversionary theories of war suggest that leaders may engage in bellicose foreign policies to divert the public’s attention from domestic problems and capitalize on a ‘rally around the flag’ type of effect. The evidence regarding diversionary theory is quite mixed. More recently, scholars have focused on situations that create opportunities for diversionary behavior, such as international rivalry and territorial disputes. This paper adds to the growing literature on diversionary conflict by considering the Ethiopia–Eritrea case and applying an opportunity-based approach. We assess whether the Ethiopia–Eritrea War (1998–2000) is consistent with diversionary explanations for the war, as many have previously claimed. 相似文献

During the transformation period of the Ottoman Empire leading to the Republic of Turkey, many conflicts took place between 1918 and 1923. These conflicts interrupted the servicing of the Ottoman war bond. The reimbursement likelihood of this bond was related to the outcomes of First World War and the hostilities. This paper analyses the impacts of First World War and hostilities on the risk assessments regarding the Ottoman war debt, using manually collected data on the price of the Ottoman war bond traded at the ?stanbul bourse between 1918 and 1925. The empirical results imply that the defeat of the Bulgarian army and the peace offer of Austria-Hungary were associated with the increasing premium demanded by investors of the bond. The victories of the Turkish National Movement and the peace offer of the Allies to end the hostilities by 1922 positively affected the likelihood of the servicing of the debt. 相似文献

Since the 2003 war in Iraq, private military and security companies (PMSCs) have become increasingly legitimate actors in modern conflicts. Despite this normative shift, rumours in March 2015 regarding the use of South African mercenaries in Nigeria to combat Boko Haram insurgents caused an international outrage, while the Nigerian government remained nonchalantly silent on the matter. This article investigates the impact of mercenaries on the conflict in the last six months of the Jonathan government. Using primary and secondary qualitative research, it assesses the role that PMSCs played in Nigeria’s counterinsurgency strategy, along with the ensuing reaction of international and local media to the outsourcing of violence to foreign companies. The article concludes that – notwithstanding the improved image of PMSCs in the world, and the actual impact of the contractors on the Nigerian counterinsurgency effort – the stigma of mercenaries continues to plague the industry, particularly on the African continent. 相似文献

The end of the 1987 Intermediate-range Nuclear Forces (INF) Treaty has the potential to plunge Europe and NATO into deep crisis. Russia’s continued violation coupled with the Donald J. Trump administration’s desire to balance against Moscow and Beijing could force a new missile debate on Europeans. Even though Washington is trying to assuage its allies, the specter of another round of INF missile deployments to Europe is not unrealistic. Meanwhile, NATO’s European members face a dilemma. Some want NATO to resolutely push back against Russia. Others want to avoid a new deployment debate, at almost all costs. The Kremlin will use these cleavages to weaken NATO. If not carefully handled, NATO’s response to the Russian missile buildup could lead to domestic turmoil in a number of European states and render the alliance ineffective for a prolonged period. Europeans need to act now and voice their preferences in the military and diplomatic domains. A number of different military options are available, below the level of deploying new INF missiles in Europe. However, Europeans need to consider trade-offs regarding crisis and arms-race stability. At the same time, it will be up to European capitals to conceptualize a new arms-control framework for the post-INF world, one that takes into account today’s geopolitical realities and the entanglement of modern conventional and nuclear forces. Given the Trump administration’s loathing of arms control, concepts of mutual restraint may well have to wait for the next US administration. In any case, that should not stop Europeans from taking on more responsibility for their own security. 相似文献

Recent anecdotal evidence from the civil wars in Somalia and Yemen suggest that water scarcity may shape the dynamics of civil wars. While a considerable body of research has examined the connection between water scarcity (such as low rainfall) and the onset of civil war, very little research has examined how water scarcity may shape the duration and outcomes of civil wars. Looking specifically at rainfall, this paper argues that changes in access to water play a key role in the duration of civil wars. As rainfall declines, there is a reduction in resources available to both the government and the rebel group, leading to a stalemate in fighting. Furthermore, this paper argues that declines in rainfall are felt more acutely by rebel groups who seek to challenge the government through conventional warfare. This paper tests these propositions using hazard models. The results provide robust support for the propositions. 相似文献

The history of the Somali Armed Forces, principally the army, forms an important part of studying the Somali civil war. Two key themes are evident from 1960: the pursuit of an irredentist agenda beyond reasonable limits, which led to the downfall of Siad Barre’s regime, and the clan divisions and agendas that Barre used to shore up his rule in the 1980s and that have bedeviled the rebirth of the Somali Army in the twenty-first century. With the twentieth-century context covered, and in some places reinterpreted, this article then focuses on the uncertain rebirth of the Somali Armed Forces since 2008, using a host of primary and United Nations official sources. Assistance efforts have been focused on Mogadishu, but limited success has been made in forming truly national armed forces. Future prospects are uncertain, but there are some signs of hope. 相似文献
