This article reviews the circumstances surrounding a relatively obscure and almost forgotten US Marine Corps and Army security enhancement operation undertaken in Panama that commenced in early April of 1988. Marines were sent to Panama to protect oil and ammunition storage facilities from potential saboteurs. By April 1989 they had reported sighting armed, uniformed intruders on at least 43 occasions and receiving gunfire or discharging their own weapons during 16 incidents. Yet despite the repeated barrages of small arms fire over the course of a year, they failed to recover enemy ammunition, bodies or body parts and their own equipment and positions displayed no signs of suffering from hostile fire. This article analyzes the events from the point of view of a veteran of the operation and highlights the role that psychological operations may have played in generating the situation.  相似文献

U.S. nuclear export policy has undergone major transformations since 1945, and the most recent change, as expressed in the July 18, 2005, India-U.S. Joint Statement, represents an especially significant shift in policy. The document reverses more than a quarter century of U.S. declaratory policy, suggesting that the current U.S. administration regards nuclear proliferation to be both inevitable and not necessarily a bad thing. This article investigates this policy shift, looking at the history of U.S. nuclear export policy and the potential ramifications of the new policy on the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The author also touches on the potential effects of the Joint Statement on Indian-Pakistani relations. Finally, it is suggested that it is not too late for India and the United States to change the new policy with more consideration for the NPT and the Nuclear Suppliers Group Initiative.  相似文献

There are conflicting views as to the relationship between a nation’s defense expenditure (DE) and its population’s income inequality (INEQ). DE, always an important part of government budget, can easily crowd out transfer payments, necessary to improve INEQ; however, these payments may also create a demand that may raise the income levels of the lower income earners. Consequently, the relationship between DE and INEQ is an important question. This paper examines the relationship between DE and INEQ in China for the period of 1989–2012. Utilizing basic cointegration and causality tests, our objective is to add to the literature by providing evidence that China’s DE, in fact, do have an impact on INEQ.  相似文献

Using the ITERATE dataset, we explore the origins of transnational terrorist activity, from 1982 through 1997, in 118 countries. We model terrorism, not as a function of a nation’s ethnic, religious or linguistic fractionalization, but as an independent measure of perceived ethnic tensions. When we control for institutional quality, evidence that political rights and civil liberties mitigate the terrorism‐producing effects of ethnic tensions exists only since 1990. Economic freedoms, on the other hand, robustly reduce the number of terrorist attacks originating in ethnically tense societies.  相似文献

In a rendez‐vous search two or more teams called seekers try to minimize the time needed to find each other. In this paper, we consider s seekers in a rectangular lattice of locations where each knows the configuration of the lattice, the distribution of the seekers at time 0, and its own location, but not the location of any other. We measure time discretely, in turns. A meeting takes place when the two seekers reach the same point or adjacent points. The main result is that for any dimension of lattice, any initial distribution of seekers there are optimal strategies for the seekers that converge (in a way we shall make clear) to a center. © 2007 Wiley Periodicals, Inc.

Conventional wisdom holds that Pakistanis are overwhelmingly opposed to American drone strikes in their country’s tribal areas and that this opposition is driven by mass media coverage of the loss of life and property the strikes purportedly cause. Using an approach based in the literature in political communication and public opinion, we argue this conventional wisdom is largely inaccurate. Instead, we contend that awareness of drone strikes will be limited because Pakistan is a poor country with low educational attainment, high rates of illiteracy and persistent infrastructure problems that limit access to mass media. Moreover, because of these same country characteristics, Pakistanis’ beliefs about drone strikes will be shaped primarily by informal, face-to-face political communication, rather than through more formal media sources. We test this argument using data that we collected by fielding a 7,656 respondent, nationally-representative survey carried out in Pakistan in 2013. The results of the statistical analysis support our arguments.  相似文献
