The article analyses the Spanish military transformation. This process started in 2004 as a means to adapt the force structure, organization and capabilities of the Spanish military to meet present and future threats in compliance with NATO’s initiatives, thus ensuring the continuity of the equipment modernization, professionalization and the adjustment of the country’s defence architecture to the post-cold war environment. A decade later, although transformation is still a priority for the Ministry of Defence, limited political will, a lack of strategic guidance, poor resource management and the effects of the economic crisis are compromising its development. This article describes the Spanish military transformation and assesses its value in adapting the country’s armed forces to the current and prospective security environment. 相似文献

This article explores how armed forces in EU member states work with and view social media in national and international settings, and what the patterns of convergence/divergence are on these issues. To that end, a questionnaire targeted at EU armed forces was constructed. An index of qualitative variation was calculated to explore the relative convergence among respondents (n = 25) on issues of risks and opportunities with using social media nationally and internationally. Consistent with previous research on European armed forces, we found higher levels of divergence than convergence. Contrary to our expectations that similar challenges, joint international standards, and membership in international organizations would foster convergence with regard to social media use in areas of deployment, we found that convergence appeared foremost pertaining to the domestic level. Policy divergence was strongest in areas of deployment. 相似文献

The paper’s main argument is that Israel’s security policy, which traditionally focused on defending its territorial integrity against regular Arab armed forces, was, by the 2010s, transformed into one that focuses on facing a variety of state- and non-state-based threats. Neo-realist explanations could neither account for the contested nature of the security debate during this period, nor the inconsistent evolution of the policy. The present study aims to solve this conundrum by introducing an alternative approach known as 4th generation strategic culture research. The paper is comprised of four parts. First, the origins and evolution of strategic culture are reviewed, with emphasis placed on the commonly accepted weaknesses that, to date, have prevented it from being used as a testable theoretical concept, and subsequently as an explanatory factor for security policy changes. The second part presents the “modernist constructivism” approach that bridges the gap between traditional constructivism and hypothesis-driven research design. Next, the paper introduces the emerging fourth generation in strategic culture literature, followed by a conceptual framework designed to resolve the inherent weaknesses of the more traditional approaches. Finally, this conceptual framework is applied to analyse the transformation of Israel’s security policy between 1982 and 2014. 相似文献

ABSTRACT There have been over 90,000 UN peacekeepers deployed around the world to 78 peacekeeping operations (PKOs) in over 125 countries since 1948. Some scholars have made the case that these missions have had a positive impact on the relationship between the military and the civilians they work for. However, other scholars have identified a negative impact on civil military relations (CMR). This paper contributes to this debate by investigating how peacekeeping has impacted civil-military relations in Latin America's most prolific contributor to peacekeeping: Uruguay. This paper finds that PKOs in Uruguay have facilitated post-transitions attempts by civilians to build first-generation control, but not second-generation control. Further, PKOs have marginally improved military effectiveness, but we find that they do not improve societal trust in the armed forces. 相似文献

ABSTRACTGrouping warships for combat has evolved greatly over the centuries. In the early 1940s, the United States Navy began to group its warships for combat in much more flexible task forces than the previous single-type-of-warship formations. This system has evolved and spread to naval forces ashore but remains fundamentally unchanged. It now covers numbers between 1 to over 1000, of which the most prominent is the first 100 or so which U.S. Navy combat forces use. The numbered fleets worldwide utilize the series covering 20-79; 1-19 and 90-99 appear to be reserved for special allocations and Commander, Pacific Fleet; numbers over 80 to the Atlantic; 100-119 for Northern Europe and briefly Tenth Fleet; the 120 series for Second Fleet as a Joint Task Force leader; the 150 series for Naval Forces Central Command; and the 180 series for Atlantic Fleet and now-Fleet Forces Command. 相似文献

ABSTRACTThe aim of the current study is to discuss which particular factors Russia considers as sufficient deterrent capabilities and whether the national defence models implemented in the Baltic countries have the potential to deter Russia's military planners and political leadership. Whilst the existing conventional reserves of NATO are sizeable, secure, and rapid, deployment is still a critical variable in case of a conflict in the Baltic countries because of the limited range of safe transportation options. However, whilst the Baltic States are developing their capabilities according to the priorities defined by NATO in 2010; which were updated after the invasion of Crimea in 2014, Russian military planners have meanwhile redesigned both their military doctrine and military forces, learning from the experience of the Russo-Georgian war, the Russia-Ukraine conflict, and other recent confrontations. Accordingly, there is a risk that the efforts of the Baltic countries could prove rather inefficient in deterring Russia. 相似文献
