The course of Anglo‐Japanese relations prior to 1914 rendered senior British policymakers nervous regarding possible Japanese aggrandisement in the Middle East. This article explores the factors which precluded British acceptance of Japanese military involvement there when, both before and during World War I, the idea was discussed. Particular reference is made to the views of the India Office and to those of Lord Curzon and the subject is analysed in the broader context of British Middle Eastern policy.  相似文献

The occupation and pacification of Bosnia-Hercegovina by Austro-Hungarian forces between 1878 and 1882 constitutes a politico-military rarity: a major colonial-style campaign waged in Europe. Yet Vienna's 1878-82 operations in Bosnia - including a hard-fought, multi-corps invasion followed by a sustained counterinsurgency campaign to put down lingering resistance to Habsburg rule - remain little known even among scholars of the region and counterinsurgency experts. However, their strategic lessons are of import today, as Vienna's battlefield successes in Bosnia brought a degree of peace and stability to the region that it has rarely known in modern times. Moreover, Austro-Hungarian military leaders waged a victorious campaign in the field that strengthened political objectives, and provided a textbook example of how to vigorously wage a counterinsurgency campaign against religiously-inspired foes in harsh terrain without undermining the occupier's political legitimacy.  相似文献

ABSTRACT

This article systematically assesses the 2014 Afghanistan Presidential Election, the first transfer of power from President Hamid Karzai to an elected successor, using provincial voting data as well as explicit data from polling centers. The analysis finds unusual voting results in the April election, where no candidate received 50%+1 votes required by the Afghan constitution, versus the voting results realized for the June ‘runoff election.’ As in other Afghan voting analyses, this article finds voting based on ethno-linguistic preferences, and interestingly found Dr. Ashraf Ghani receiving almost all the swing votes in the runoff election even though the other leading candidate from the April election all endorsed Dr. Abdullah Abdullah. More importantly, however, the research presented here clearly finds extremely strange voting patterns. For example, the polling data center analysis finds 606 polling places where Ghani received all 600 votes and Abdullah received none and another 900 polling centers that gave virtually all its votes to Ghani. These results in combination with other analyses raise the very real possibility that the election results were illegitimate. The article concludes with a discussion of the implications of the research to future Afghan elections and their processes as well as to the long-standing conflict in the country.  相似文献

The lessons from the two French counterinsurgencies, Indochina and Algeria, give rise to a new understanding of the projection of airpower in remote and hostile environments and the purpose, design, and use of aircraft in counterinsurgency. In both Indochina and Algeria, the campaigns were ones of poverty, and it is their imaginative management under severe resource constraints that provides thoughtful and applicable lessons for today. In both cases, airpower held the promise of delivering victory and solving the resource issue. In Indochina, acquisition of the needed aircraft, operating knowledge, and experience came too slowly to realize this promise. In Algeria, the French embraced the lessons from Indochina and were quite successful and innovative in the use of airpower. The lessons can be reduced to four requirements: (1) a network of airfields for liaison, ground-support, and intra-theater airlift to enable effective air support of ground forces; (2) a solid, reliable, and simple ground-support aircraft capable of operating from forward airfields within range of ground engagements; (3) a capable intra-theater heavy-lift transport to supply the extended ground forces; and (4) helicopter capability to enhance tactical troop mobility and support.  相似文献
