In the global war against terrorism key questions need to be asked concerning how Al Qaeda is reorganizing and who will be leading it. In the absence of, at the very least adequate open source data, how can we answer these vital questions and predict the next evolution of this deadly menace? One possible solution is to study the emergence and evolution of leadership within another terrorist organization. Based on an analysis of the Provisional Irish Republican Army, it is assessed that there have been at least two and possibly three distinct generations of leadership in that group. It is important to note, however, that although these three generations have emerged sequentially, they may well all be in positions of power at the same time. These generations are designated as; early or founding leaders; follow-on and continuity leaders; and embryonic leaders. Such analysis will not tell us whom the new and emerging leaders of Al Qaeda actually are but it might help us to frame the right questions to ask our intelligence collectors.  相似文献

The events of the 1973 Arab‐Israeli War serve as an early indicator of Iraqi leader Saddam Hussein's willingness to use military power to address foreign policy concerns. In that war, Iraq intervened on the Syrian front with an armored division, other supporting units, and over 100 aircraft. This intervention, which occurred despite severe political and military difficulties, was larger than any previous Iraqi contribution to the anti‐Israeli struggle. Baghdad later asserted that Iraqi forces had saved Damascus from possible Israeli occupation, and these claims have been widely repeated by a variety of authors of different nationalities with various degrees of agreement or skepticism. Nevertheless, Iraqi claims to have saved Damascus from Israeli capture are false since the Israelis did not view the seizure of the city as important to their strategy for victory. Rather, the Iraqi presence on the Golan Heights was useful to the Arab war effort as one of many factors helping to delay the Israeli advance and prevent some important Syrian targets from being placed within artillery range of the Israeli force. Iraqi military shortcomings were well highlighted in this conflict, and many were repeated in the early stages of the war with Iran.  相似文献

The material in this overview is drawn from selected abstracts that appear in the Center for Nonproliferation Studies’ nuclear and missile databases. Transactions of nuclear and missile technologies, parts, and materials are listed according to the recipient country. Other developments are listed according to the country where the event or development took place. The new, streamlined format of this section indicates a decision by the Monitoring Proliferation Threats Project to focus on only key information in the overview and to offer more in‐depth analysis in the “Reports” section of the journal.  相似文献

The estimation problem of normal tail probabilities is considered. The form of generalized Bayes estimators is derived and the asymptotic behavior of the mean square errors is studied. This study shows that the best unbiased estimator, a formula for which is given, is superior to the maximum likelihoood estimator or to a class of generalized Bayes procedures for large parametric values, but can be significantly improved for moderate values of the parameter.  相似文献

In this paper we investigate a form of rational behavior in response to an oligopoly pricing problem where only one buyer is involved. We investigate the problem from the standpoint of the seller who wants to maximize his gain from the transaction. In particular, we deal with the problem of one seller's response to an invitation to submit a sealed (i. e., noncooperative) bid to a government or other dominant purchasing agency for supplying a specified bundle of goods and services for which either (1) no other demand exists, or (2) the terms or quantities involved cannot, at least in the short run, be obtained from another source. Although treated from a normative standpoint, i. e., what bid the supplier should make, the paper also has implications for the buyer's behavior and oligopoly-monopsony pricing in a more general sense.  相似文献

This article examines the ambiguous role played by the Cyprus Police Force during the Greek Cypriot insurgency against Britain between 1955 and 1959. A multiethnic force policing a multiethnic society, the CPF struggled to fulfill its duties. Greek Cypriot officers became ineffective as sympathy for, or fear of insurgents undermined their ability to function. Some collaborated, others resigned. Those who stayed became targets of their own people. Turkish Cypriot officers, recruited in greater numbers to compensate for a reduction in Greek Cypriot officers, worked to enforce the law, but exacerbated intercommunal relations in doing so. In spite of the peculiar conditions present in Cyprus, the case has valuable implications for contemporary policymakers on the vulnerabilities inherent in the use of local police forces to restore law and order in ethnically divided societies.  相似文献

Scholars and policymakers argue that violent actors – termed ‘spoilers’ – pose a significant threat to civil war peace agreements. Yet existing research, which is overly reliant on single-case studies, has not effectively determined how prevalent spoiling is, or thoroughly examined what its ultimate effects are on peace agreements. This article draws on a newly constructed cross-national dataset of spoiling following 241 civil war peace agreements in the post-Cold War era to analyze spoiling. It finds that spoiling intended to terminate an agreement is not as common as typically assumed, but still plagues a sizeable number of peace agreements. Moreover, most actors who resort to this strategy typically fail in their goals and the agreement is not at risk, despite the high publicity and attention given to these threats. Yet particular types of actors, most notably paramilitaries and state security forces excluded from the agreement, can pose a significant threat to peace.  相似文献
