US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military. 相似文献

ABSTRACTThere have been calls for the abolition of nuclear weapons from the day they were invented. Over the last fifteen years, some indications can be found that such calls have been getting louder, among them Barack Obama's famous 2009 speech in Prague. In this article, we investigate if support for a comprehensive norm that would prohibit development, possession, and use of nuclear weapons is really growing. To assess the current status of that norm, we use the model of a “norm life cycle,” developed by Martha Finnemore and Kathryn Sikkink. We then analyze 6,545 diplomatic statements from the review process of the Treaty on the Non-Proliferation of Nuclear Weapons as well as from the UN General Assembly First Committee on Disarmament and International Security, covering the years 2000 to 2013. The evidence shows that a comprehensive prohibition can be considered an emerging international norm that finds growing support among states without nuclear weapons and nuclear weapon states alike. Only a core group of states invoke the norm consistently, however. This leads us to conclude that the “tipping point” of the life cycle, at which adherence to a new norm starts to spread rapidly, has yet to be reached. 相似文献

The current nuclear nonproliferation order is no longer sustainable. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) has weakened considerably over the years, with nuclear have-nots displaying increased dissatisfaction with the status quo. Meanwhile, demands for civilian nuclear technology have led to increased proliferation risks in the form of dual-use technologies. Arms control as we currently understand it—piecemeal treaties and agreements—is no longer sufficient to address the growing threat of proliferation and the frailty of the NPT. This article calls for a bolder nonproliferation agenda pursuing multilateral nuclear disarmament. Disarmament is, in fact, technologically achievable; a lack of political will stands as the only remaining roadblock to a world free of nuclear weapons. A better understanding of the technological feasibility of disarmament, as well as recognition of the diminishing strategic value of nuclear weapons, will help to erode this political reluctance. 相似文献

After the conclusion of the 2008 Preparatory Committee (PrepCom) for the 2010 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Nonproliferation Review interviewed Ambassador Yukiya Amano of Japan, who presided over the 2007 session of the PrepCom in Vienna. He provided valuable insights into his preparations for the PrepCom and shared his thoughts on some of the most pressing issues that confronted his chairmanship and the PrepCom as a whole. The interview also provides useful perspectives on the future of the strengthened review process. 相似文献

The nuclear weapon states (NWS) have different perspectives on the desirability and feasibility of a world without nuclear weapons. A review of each of the current nuclear doctrines, postures, and disarmament policies of the five NWS shows that there is a clear divide between them, with some showing relatively determined leadership (the United States and the United Kingdom) and others expressing skepticism, if not complete disinterest (France, Russia, and China). Nevertheless, the prospects for progress on disarmament by the NWS at the 2010 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons remain reasonably good. Yet complete success will require much time as well as sustained and applied efforts from the NWS, first and foremost to improve their performance as international security guarantors. 相似文献
