Strategy is matching means and ends. If the ends desired in Afghanistan are about al Qaeda, the counterterrorism option is the best fit in terms of means. It is sustainable, always crucial in prolonged conflict, as it limits the expenditure of U.S. blood and treasure. This article fills a gap in the existing strategy debate by detailing what a counterterrorism option would be in terms of force structure and operations.  相似文献

Al Qaeda leaders have often stated their desire to attack the state of Israel. But, while the intent and imperative of killing Israelis and Jews features prominently in al Qaeda rhetoric, it has rarely translated into operational attacks on the state of Israel, its citizens abroad, or Jews more generally.  相似文献

The World War II experience of public service created a generation of scholars who devoted themselves to policy-relevant research during the early Cold War. The Vietnam War led to a split between the two groups, and scholars and policymakers today inhabit two different worlds. Fortunately, it appears as though the relationship between the world of ideas and the world of action is entering a new phase. Both the academy and the nation would be better off if scholars were more involved in topics of interest to policymakers. However, building a closer relationship between these two worlds faces challenges.  相似文献

When General Creighton Abrams took command of U.S. forces in Vietnam a better war resulted from his superior understanding of the war and more effective conduct of it, including improvement of South Vietnam's armed forces and emphasis on pacification. As American forces were progressively withdrawn, the South Vietnamese took on more and more of the load, winning the counterinsurgency war and fighting valiantly and effectively against the enemy's conventional invasion until the United States Congress drastically reduced materiel and financial assistance at the same time communist forces received massively increased support from their patrons. Thus, inevitably, South Vietnam succumbed.  相似文献

For the war in Vietnam, real perspective can only come when we extricate ourselves from the historical quagmire and start evaluating the conflict as more than just a mistake that deserves our condemnation.  相似文献

Yemen, the poorest and most populous country on the Arabian Peninsula, has long been a prime candidate to join the failed state club. After the wave of uprisings sweeping through the Middle East reached the country in early 2011, the already high levels of instability and violence reached new heights and threatened to accelerate a steady march towards collapse. Even though a variety of scenarios can be identified for the future of Yemen, the most likely paths all imply a period of prolonged instability. This will carry significant consequences for regional and international security, in particular, by providing al Qaeda's local franchise with an attractive safe haven from which to plan and launch operations.  相似文献
