In its colony of Angola, Portugal during its colonial wars (1961–1974) was able to exploit the economic dependence and divided population loyalties of its hostile neighbours the Congo and Zambia as well as the cleavages within the nationalist movements to prevent a crippling insurgency. The rulers of both countries were largely dependent on Angola for trade, and were eager to have the side effects of the robust Angolan economy with its 11% annual growth brush off on their own moribund ones. While relationships were never comfortable, the sponsors of revolution were forced to reign in their ‘freedom fighters’ in order to maintain the functioning of their export-dependent economies. Portuguese leadership also played a vital role, as it was able to bring together diverse elements of national power in a concerted policy for dealing with these enemies, whether they were insurgents or their sanctuary countries. This policy of leveraging national power and playing on the vulnerabilities of its opponents worked well during its war in Angola and still holds valuable lessons for countries that find themselves in similar circumstances.  相似文献

On 4 January 1961 in Baixa do Cassange, in the north of Angola, the blacks who worked in the cotton fields began a strike. The army with air support was called to quell the rebellion, and the article emphasizes the importance of air support tethered to the ground forces, particularly in a remote and vast area of operations in the tropical rainy season. In this case, the support originally came in the form a squadron of Lockheed PV-2 Harpoons from Luanda, some 300 kilometers away. These open-ocean reconnaissance aircraft and their crews were ill-suited for the task. When this became apparent, four small Auster D5/160s were relocated from Negage to Malange, among the ground forces. The Austers flew reconnaissance missions over the troubled zones, dropped provisions and messages to the advancing ground forces, and served as a backup communications link. When the strike ceased after three weeks, the Austers assumed a humanitarian role in support of the starving population. The conclusion is that air support to ground forces is indispensable, must be properly tailored to the job, and must operate as an integral part of the ground forces.  相似文献

ABSTRACT

The armed resistance offered by the Organization of Ukrainian Nationalists (OUN) to the Soviet state was the toughest internal political challenge that the Soviet regime faced from World War II to the 1980s. However, OUN’s grand strategy was based on self-delusion and was, therefore, always irrational. It resulted in misinterpretation of the sentiments of Ukrainians and the international situation, collaboration with Nazi Germany despite incompatible goals, counterproductive ethnic violence and sweeping terror against alleged Soviet collaborators. Local civilians rather than the representatives of the Soviet regime were OUN’s primary target; this alienated most residents of Western Ukraine.  相似文献
