Because of its origins in a sort of anti-Elizabethan paranoia against centralised government, the United States is poorly set up institutionally to cope with the major danger to itself in the twenty-first century: the threat posed by Islamist terrorism. The Director of Central Intelligence is neither central nor fully directing. A large part of the intelligence community, especially in terms of budgets and supervision, is outside his direct control. There is a 'waters edge' separation between the Federal Bureau of Investigation (FBI) and the CIA. Essentially the CIA collects foreign intelligence and counter-intelligence overseas. The FBI, primarily a crime-oriented organisation, has had only a secondary function of domestic counter-intelligence. It is a case-oriented agency focused on establishing past facts in order to bring suspects to justice. It is psychologically ill-adapted to conceptualising threats that lie upstream, that is, in the future. In this context, September 11 can be most properly described as a failure of imagination. Remedies being proposed range from creating an internal security service à la Britain's MI5 to establishing a semi-autonomous domestic counter-intelligence agency within the FBI. In the field of covert action, intelligence in the twenty-first century likely will be characterised by what could be termed an offensive hunt strategy. Put in another way, intelligence operatives in the twenty-first century will become hunters, not gatherers. They will not simply sit back and gather information that comes in, analyse it, and then decide what to do about it. Rather they will have to go and hunt out intelligence that will enable them to track down or kill terrorists. This will involve sending operatives into countries with which we are not at war, indeed in some cases countries with which we have correct relations. In many circumstances, however, terrorist leaders will be hunted down with the help of host country elements. The likelihood is that this new strategy will be implemented primarily in terms of Special Forces operations aided by CIA elements. Modalities will have to be worked out between the Department of Defense and the CIA as to how such offensive hunt operations are to be carried out and how congressional oversight will be exercised.  相似文献

Although on Spain's periphery, Catalonia has often held a central position in Spanish politics. In dealing with the Catalan question, politicians in Madrid and Barcelona have had to grapple with different models of state structures. Some have even attempted to consider the issue in terms of greater European solutions. At the end of the 20th century, Europe's regions are having to consider their role not just within the traditional states, but also within the new European framework. The Scottish movement has now found itself in a position to affect British politics. The long tradition of Catalan thought on statecraft, and the influence Catalonia has had on the Spanish state, can serve as useful examples for the traditionally more marginalised Scots. Both Scots and Catalans face the question of defining their own identity, the identity of the state and the identity of Europe. In two decades of British politics, the SNP has also shifted to define itself within a greater European context.  相似文献

The cost of producing multifamily affordable housing may differ based on development type. Past attempts to compare the costs of producing multifamily housing through new construction or acquisition-rehab have been limited by an inability to adjust for variations in unit quality among different projects. The authors overcome this challenge by estimating the costs of developing and maintaining a property over a 50-year life cycle. Applying this approach to a convenience sample of 269 properties, the authors find new construction associated with life-cycle costs that are 25% to 45% higher than those of acquisition-rehab.  相似文献
