The role of the British Army in Northern Ireland during Operation Banner (1969–2007) is an instructive case study of counterinsurgency operations as well as an important chapter in recent British military history. Given troops deployed to the province as aid to the civil power, it is particularly useful in discussions about the principle of minimum force. This article seeks to explore the issue of minimum force through the example of Operation Motorman, the Army's successful attempt to remove the barricades, which had established so-go areas for the security forces in Northern Ireland. 相似文献

This article argues that aspirations of maintaining a dominant influence over sub-Saharan security issues has spurred the French and British leadership of European Union (EU) foreign and security policy integration, just as it has informed military capability expansions by the armed forces of the main EU powers. While Europe's initial African focus was on stabilising a continent marred by state failure, civil wars and genocides, changes in the global security context, especially the shift towards multipolarity manifest in China's growing engagement, has prompted a complementary focus on deterring other powers from making military inroads into the subcontinent. Hence Europe's sub-Saharan security focus is shifting from stabilisation towards deterrence. This helps explain recent military procurements which, in spite of the extremely challenging fiscal position of most EU member states, feature large-scale investments in long-range deterrence capabilities. 相似文献
