Tomas Kucera 《Journal of Military Ethics》2017,16(1-2):20-37
Humanitarian operations may pose challenges to which armed forces prepared for warfighting seem rather ill-equipped. It is the aim of this article to examine in what way military ethics should be adapted to humanitarian tasks. Two ideal types of military ethics are defined here: warfighting and humanitarian. The warfighting ethic is supposed to maximise the utility of the military in war and combat and to that end utilises the virtues of loyalty and honour. In contrast, humanitarian obligations require to a larger extent the development of personal integrity and an ability to follow one’s own conscience. The adaptation of military ethics is demonstrated in the case studies of the UK armed forces and the German Bundeswehr. Whereas the moral code of the UK armed forces remains anchored in the principles of the warfighting ethic, the case of the Bundeswehr presents a military ethic closely approximating the humanitarian ideal type. 相似文献

This article reappraises the two most-studied country cases of military outsourcing: the USA and the UK. It argues that the contemporary wave of military contracting stretches back to the beginning of the cold war and not only to the demobilisation of armies in the 1990s or the neoliberal reforms introduced since the 1980s. It traces the political, technological and ideational developments that laid the groundwork for these reforms and practices since the early cold war and account for its endurance today. Importantly, it argues that a persistent gap between strategic objectives and resources, i.e. the challenge to reconcile ends and means, is an underlying driver of military contracting in both countries. Contemporary contracting is thus most closely tied to military support functions in support of wider foreign and defence political objectives. Security services in either state may not have been outsourced so swiftly, if at all, without decades of experience in outsourcing military logistics functions and the resultant vehicles, processes and familiarities with public-private partnerships. The article thus provides a wider and deeper understanding of the drivers of contractualisation, thereby improving our understanding of both its historical trajectory and the determinants of its present and potential futures. 相似文献

How have European cross-border defence industrial mergers and acquisitions affected domestic procurement bias among the major EU powers? This article departs from the findings of Andrew Moravcsik more than two decades ago suggesting that major West European states had no ingrained preferences for defence industrial autarchy. When cross-national armament projects were derailed, this could be attributed to political efforts of national defence industrial champions favouring purely domestic projects. As former national champions join pan-European defence groups, their preferences are likely modified. Does this shift procurement towards non-European “off-the-shelf” solutions which, according to Moravcsik, are favoured by defence departments? Or does it give impetus to a stronger preference for European as opposed to domestic systems? In this article, procurement patterns in the aftermath of cross-border defence industry consolidation will be analysed. Procurement bias is assessed in two industry segments characterised by pervasive consolidation. 相似文献
