Scholarly research and publication in many countries has made the Korean War not only remembered, but also better understood. Material from Russia and China have been especially helpful in adding nuance and detail to now‐dated writing about the war's causes. Much more work needs to be done on Korean politics and the 1952–53 period, but in all the scholarship simply confirms the shared responsibility of all the belligerents ‐ including the Koreans ‐ in starting and continuing the war.  相似文献

Despite all the talk of ‘hearts and minds’ being the key to counterinsurgency, local public opinion is rarely studied and when it is, it often yields surprising conclusions. Through analyzing polling data from Vietnam, Iraq and Afghanistan, this article shows that public opinion is less malleable, more of an effect rather than a cause of tactical success, and a poor predictor of strategic victory. As a result, modern counterinsurgency doctrine’s focus on winning popular support may need to be rethought.  相似文献

Multiple ethnic insurgencies have existed in Myanmar since independence. The military junta's response has been extremely brutal at the tactical level, but has shown some political astuteness at the strategic level, with a series of ceasefires with most of the ethnic groups. Despite these ceasefires – most of which have resulted in the continued existence of quasi-independent armed groups – other ethnic movements have continued their armed operations. The overall strategic picture is one of stalemate, with the ethnic movements continuing to exist, but with few realistic prospects of expanding their operations.  相似文献

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
