ABSTRACT

German security and defence policy has undergone substantial transformation. This transformation requires an unprecedented level of political leadership, suggesting that Germany needs to solve the dilemma of how to supply leadership to increasingly demanding partners. What are the conditions under which German leadership can unfold in security and defence policy? To what degree do German role-conceptions of international agency and role-expectations of German leadership coincide? What kind of leadership outputs are produced? This study offers a comprehensive analysis of German security and defence policy in terms of supply (role conceptions) and demand (role expectations). We outline three leadership role conceptions present in the German strategic debate, which we then assess in the context of the Wendtian theory of cultures of anarchy. We then analyse Berlin's leadership in terms of outputs via the case study on Anchor Army and the Framework Nations Concept. We conclude that while Germany has tried to match leadership role expectations both rhetorically and in action, Berlin's leadership inputs have so far been insufficient. This has led to an imbalance in terms of role conceptions and expectations hampering effective German leadership in security and defence policy.  相似文献

Historically, insurgency is one of the most prevalent forms of armed conflict and it is likely to remain common in the foreseeable future. Recent experiences with counterinsurgency in Iraq and Afghanistan offer many lessons for future counterinsurgents, but the discourse on the subject continues to be mired in a traditional dichotomy pitting population-centric approaches to counterinsurgency against enemy-centric approaches. Historical analysis suggests that this traditional dichotomy is not a sufficiently nuanced way to understand or plan for such operations. Instead, discussions of counterinsurgency should focus on two dimensions: actions (use of physical force vs. political or moral actions) and targets (active insurgents vs. insurgent support). This perspective divides the space of possible counterinsurgency efforts into four quadrants, suggesting that effective counterinsurgency campaigns find a balance of effort across the four quadrants that is well matched to the specific context.  相似文献

Strategists and military professionals have previously questioned many of the methodological (theoretical underpinnings, the principles, and rules applied by the discipline) decisions associated with American military strategy, but the direction this essay takes is above and beyond the common methodological rivalries in how we pursue strategic desired future states. To get beyond methodological disputes entirely, we must consider thinking about our thinking as an organization on American strategy. Thus, this article hovers between philosophies, organizational theory, as well as our usually unquestioned belief in something called “strategy”. Questioning things about our basic understanding of the world tends to trigger strong organizational defense mechanisms, for good reason. Critical reflection at deep levels puts our worldview, and our role within it at stake. Nonetheless, as strategic disappointment emerges over multiple complex conflict developments, even the most cherished and guarded choices on how the world ought to work are ripe for critical inquiry. This essay examines the limited single strategic paradigm of the US defense industry and how the latest American National Security Strategy and Army Future Operating Concept (Win in a Complex World through 2030) presents a flawed strategic position. This essay presents valid alternative strategies that operate within different paradigmatic constructs.  相似文献

This paper examines the interaction between a growth-oriented terrorist organization and an uninformed government based on a two-period signalling game. Combining the signalling game and organizational growth approaches of previous contributions, this paper shows that, if a terrorist group follows a growth strategy, it has an incentive to appear weaker than it is by mimicking the behaviour of a smaller organization. Depending on its beliefs about the extent of the terrorist threat, it can be optimal for a government to spend more on second-period counter-terrorism measures if it is not attacked in the first period than if it were attacked.  相似文献

We undertake inference for a stochastic form of the Lanchester combat model. In particular, given battle data, we assess the type of battle that occurred and whether or not it makes any difference to the number of casualties if an army is attacking or defending. Our approach is Bayesian and we use modern computational techniques to fit the model. We illustrate our method using data from the Ardennes campaign. We compare our results with previous analyses of these data by Bracken and Fricker. Our conclusions are somewhat different to those of Bracken. Where he suggests that a linear law is appropriate, we show that the logarithmic or linear‐logarithmic laws fit better. We note however that the basic Lanchester modeling assumptions do not hold for the Ardennes data. Using Fricker's modified data, we show that although his “super‐logarithmic” law fits best, the linear, linear‐logarithmic, and logarithmic laws cannot be ruled out. We suggest that Bayesian methods can be used to make inference for battles in progress. We point out a number of advantages: Prior information from experts or previous battles can be incorporated; predictions of future casualties are easily made; more complex models can be analysed using stochastic simulation techniques. © 2000 John Wiley & Sons, Inc.
