As a result of the migration crisis of 2015–2016, the management of mass migration and border control became militarised in Central Europe, and this process has also reshaped the dynamics of multinational defence cooperation in the region. Accordingly, while the so-called Central European Defence Cooperation (CEDC) was created by Austria, Croatia, the Czech Republic, Hungary, Slovakia and Slovenia in 2010 to support NATO and EU capability development projects via defence cooperation, after the migration crisis it became the major Central European forum for military cooperation against irregular mass migration. Although many defence officials in the region are not necessarily enthusiastic about this development, the Central European political environment and also practical defence considerations pushed the defence ministries of CEDC countries towards deeper cooperation on border control, as well as better coordination with ministries of interior affairs on the national and the regional levels.  相似文献

The post-communist countries transition from the Warsaw Pact style of platforms and systems to Western-compatible capabilities has never been an easy task or a process without conflicts. This was no different for the Visegrád countries either, in which case the Hungarian Gripen procurement stands out. After much debate, Budapest decided to modernize its fighter fleet with the not battle tested Swedish-made Gripen fighter aircraft. This decision received several critiques due to the lack of transparency in the selection process and the initial lack of NATO-required systems. Subsequently, the fleet has had to operate in a financially demanding environment. Moreover, the air force has lost two aircrafts in accidents. Now that the jets are in the middle of their envisaged life cycle, it is more than appropriate to answer the question if the Gripens can utilize their full combat potential or will they fail the test of time?  相似文献

ABSTRACT

The recent rise in the defence budgets among the NATO members reawakens the free-riding dilemma. This article provides an analysis of the defence spending of two new member states, the Czech Republic and Lithuania. Based on the free-riding theory, we explain why some of the new NATO members decide to increase their defence budgets (Lithuania), and others do not (Czech Republic). In contrast to the majority of works which focus either on the US as the biggest spender or on the “old” members of the Alliance, we explain under what circumstances some of the small European states who became new NATO members started to increase their defence budgets even though they do not have to, and the literature suggests that free-riding is easier. In the process, we identify three crucial factors that in?uence the decision-making process in this regard: the level of threat perception, economic situation, and the US pressure.  相似文献

In 1955, the New Zealand government authorised the creation of a Special Forces unit to operate with British forces in Malaya to counter a communist-inspired guerrilla insurgency. Drawing upon the operational experiences of the New Zealand SAS largely taken from the Cold War period, and underpinned by Colin Gray's Special Forces essentials of ‘economy of force’ and ‘expansion of choice’, this article will show how New Zealand's SAS is now accepted not only as a respected and relevant part of the nation's military capability, but also empowers its political decision-makers with the confidence to take on significant, and at times difficult, strategic foreign-policy choices.  相似文献

Defence expenditures have both costs and benefits to the economy. The costs of defence expenditures are mainly emphasized as opportunity costs. On the other hand, defence spending may have growth‐promoting potential benefits: a rise in defence spending may result in a higher aggregate demand, production and employment. This paper examines empirically the effects of military expenditures on economic growth for Middle Eastern countries and Turkey, for the time‐period 1989–1999. The relationship between military expenditure and economic growth is investigated by using cross‐section and dynamic panel estimation techniques. Empirical analysis indicates that military expenditure enhances economic growth in the Middle Eastern countries and Turkey as a whole.  相似文献

This paper provides a methodology for estimating the economic impact of defence spending at a sub‐regional level. It does so by calculating the income and employment generated by Britain’s Royal Navy and associated defence activities in the City of Portsmouth and its surrounding area, during the financial year 2003–2004. In an era of military consolidation, the paper offers an insight into the multifaceted impact of defence‐related expenditure. Hence, it presents a generic framework that could prove useful to other researchers when seeking to measure the sub‐regional impact of naval, airforce and army facilities in other national contexts.  相似文献

单舰防空是水面舰艇编队防空的基础.从水面舰艇单舰防空作战能力的基本内涵出发,按照水面舰艇单舰防空作战能力所包含的3个要素,即防空导弹作战能力、防空火炮作战能力和电子干扰装置作战能力,构建了水面舰艇单舰防空作战能力评估指标体系,针对评估指标的定性定量特性,引入云重心评估法对某水面舰艇单舰防空作战能力进行了评估.结果表明,该模型计算简便、通用性强,为解决军事领域类似问题提供了思路和方法.  相似文献
