Forecasting a Hurricane: Israeli and American Estimations of the Khomeini Revolution

The surprising ‘Arab Spring’ raises the question as to what would enable national intelligence to provide high quality warnings prior to the eruption of popular revolutions. This article uses new sources of evidence to trace and explain Israel's success in comparison to US failure at correctly estimating the course of the Iranian Revolution in 1977–79. In explaining this variance, the article shows that it was mainly the result of the intimate acquaintance of Israel's representatives in Iran with the local language, history and culture, as well as the ability to communicate with locals – tools which the Americans completely lacked.     

A Quarter Century of ‘Transitory Power-Sharing’. Lebanon’s Unfulfilled Ta’if Agreement of 1989 Revisited

Most countries of the Arab Mashrek are multi-ethnic and multi-sectarian. In recent years, most of them have experienced violent clashes between groups that frame their conflicts along ethnic-sectarian lines. This article investigates the Lebanese Ta’if Agreement of 1989 as a crucial case study of how to manage such conflicts through a transitory power-sharing arrangement. It presents several provisions of this agreement that adhere to three different approaches of how to deal with such conflicts: the consociational and the centripetal models of power-sharing as well as the integrationist paradigm. It thereby seeks to develop a theoretical argument about chances and risks of transitory power-sharing in deeply divided societies and derives some general lessons for managing conflicts in the Middle East.

Rethinking military behavior during the Arab Spring

Why did some Arab militaries remain loyal to authoritarian rulers amid mass uprisings during the Arab Spring while others defected to the opposition? One popular explanation shows this variation with reference to the degree of military institutionalization: institutionalized militaries defected, while patrimonial militaries remained loyal. This article argues that the institutionalization hypothesis does not provide a complete account of the mechanisms through which the degree of military institutionalization leads to either defection or continued loyalty. This shortcoming stems from the fact that scholars have treated military institutionalization as a catch-all concept for three distinct variables: ethnic stacking of the military, patronage distribution, and organizational factionalization. Examining the interaction between these variables highlights the mechanisms through which military defection occurs, and therefore that disaggregating institutionalization into its component parts provides a more complete explanation of military behavior during the Arab Spring.     

Allies at arm’s length: Redefining Egyptian–Soviet relations in the 1967 Arab–Israeli war

This article examines Egyptian–Soviet relations in the run up to the 1967 Arab–Israeli war. It argues that Egypt and the Soviet Union stumbled into brinkmanship with little coordination and no agreement on common objectives or goals. The article demonstrates how frustration and mutual disappointment were recurring features of the interactions between the two allies during the critical weeks prior to the war. In doing so, the article exposes new aspects of how Cairo and Moscow managed their alliance and assesses what that means to our understanding of the origins of this transformative war. These conclusions challenge revisionist accounts that attribute the start of the war to Egyptian–Soviet collusion and some traditional narratives that present the Soviet Union as an enterprising risk-taker invested in regional brinkmanship. The article draws heavily on Egyptian and Arabic language sources to examine Egyptian–Soviet interactions during this key period of Middle Eastern history.     

Comparative analysis of Arab Spring determinants

The Arab Spring, a pro-democracy uprising that has been sweeping through North Africa and the entire Arab world since 2010, has been described as a cataclysmic revolutionary wave that has left the overthrow of political regimes in its wake. Studies have comprehensively x-rayed the political and socio-economic circumstances that gave rise to the uprising. Apart from the impact of the uprising on political developments and democratic governance in the Arab world in particular and the world in general, the circumstances that resulted in the revolutions constitute empirical security implications for Nigeria. This is the focus of this article. Using the Ibrahim Index of African Governance (IIAG) and other selected indicators, this article draws a comparative analysis of the key factors that led to the uprisings in Egypt, Libya and Tunisia, pointing out areas of social and security tensions in Nigeria. Based on these findings, it points out the urgency of and imperative for security sector reforms in Nigeria.     

An exact method for finding shortest routes on a sphere,avoiding obstacles

On the surface of a sphere, we take as inputs two points, neither of them contained in any of a number of spherical polygon obstacles, and quickly find the shortest route connecting these two points while avoiding any obstacle. The WetRoute method presented here has been adopted by the US Navy for several applications. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 374–385, 2016

Decentralising authoritarianism? The international intervention,the new ‘revolutionaries’ and the involution of Post-Qadhafi Libya

In 2011, Libya became the only country of the Arab Uprisings where NATO and the Arab League intervened militarily, ostensibly to protect the civilian population, but in reality in support of the opposition National Transitional Council. This article argues that, since 2011, Libya has transitioned from Qadhafi’s centralised authoritarianism to a new decentralised authoritarianism where multiple centres of power coexist and sometimes overlap, while leaving room only for formal democratic institutions. This is the result of decisions taken by the ‘revolutionaries’ after the overthrow of the dictator, and a consequence of long-standing features of the Libyan state and society.     

The practice and theory of British counterinsurgency: the histories of the atrocities at the Palestinian villages of al-Bassa and Halhul, 1938–1939

This article details two largely unreported atrocities by British forces operating against Arab rebels during the Arab revolt, 1936–9, at the Palestinian villages of al-Bassa and Halhul. It then examines the military-legal system that underpinned and authorised British military forces operating in aid of the civil power, suggesting that the law in place at the time allowed for a level of reprisals and punitive actions, such as happened at al-Bassa and Halhul. The article does not conclude that the law allowed for atrocities but it does argue that it gave a basic form and understanding to an operational method that was brutal and could lead to atrocities. It thus tests the idea in much of the literature on counterinsurgency that the British were restrained and used minimum force when compared to other colonial and neo-colonial powers fighting insurgents.     

Yield randomness,cost tradeoffs,and diversification in the EOQ model

Existing production/inventory models with random (variable) yield take the yield distribution as given. This work takes a step towards selecting the optimal yield randomness, jointly with lot sizing decisions. First, we analyze an EOQ model where yield variance and lot size are to be selected simultaneously. Two different cost structures are considered. Secondly, we consider source diversification (‘second sourcing’) as a means of reducing effective yield randomness, and trade its benefits against its costs. Conditions for the superiority of diversification between two sources with distinct yield distributions over a single source are derived. The optimal number of identical sources is also analyzed. Some comments on the congruence of the results with recent JIT practices are provided.     

India and Israel: emerging partnership

The absence of formal diplomatic relations between India and Israel from India's hesitant recognition of Israel in 1950 and the establishment of full relations in January 1992, was the result of a complex interplay between two sets of tensions. The first involved the Arab–Israeli dispute, and India's sympathies with a post-colonial Arab world and with the Non-Aligned Movement; the second involved accommodating Muslim opinion within India. Normalization has proceeded more strongly as the growth of Hindu nationalism has weakened Muslim leverage on Indian foreign policy.     

Iraq's role in the 1973 Arab‐Israeli War

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.

ACQUIRING FOREIGN NUCLEAR ASSISTANCE IN THE MIDDLE EAST

The United Arab Emirates (UAE) has laid out an ambitious plan to become the first Arab country to possess a civilian nuclear energy program. Central to that effort has been the Emirati government's ability to obtain foreign nuclear assistance. This article traces the UAE's strategies for overcoming the obstacles that stood in the way of nuclear suppliers providing assistance. It examines the approach taken by the UAE to assuage the safety and security concerns of nuclear suppliers, how the UAE leveraged its alliances with France and the United States to obtain their cooperation, and its strategies for engaging domestic interest groups in supplier states. The generalizable elements of the UAE's strategies are discussed and used to provide insight into the prospects for other Middle Eastern states' bids to obtain similar assistance. The article concludes with a discussion of the potentially transformative aspects of the strategies employed by the UAE in shaping other countries' pursuit of nuclear energy in the region.     

Guns and butter? Military expenditure and health spending on the eve of the Arab Spring

We examine the validity of the guns-versus-butter hypothesis in the pre-Arab Spring era. Using panel data from 1995 to 2011 – the eve of the Arab uprisings – we find no evidence that increased security needs as measured by the number of domestic terrorist attacks are complemented by increased military spending or more importantly ‘crowd out’ government expenditure on key public goods such as health care. This suggests that both expenditure decisions were determined by other considerations at the government level.     

The impact of defence expenditures on Arab industrial development

The purpose of this paper is to examine the role of military expenditures in affecting the pattern of Arab industrial development. In doing so, it attempts to determine whether military expenditures have stimulated increased levels of industrial output, or whether, through diverting resources away from industrial activity, they have depressed the expansion of the region's industrial diversification.

By the use of factor and regression analysis, the main finding of the study is that defence expenditures in the Arab world have been somewhat neutral in impacting on industrial output. In contrast, the study found that non‐defence expenditures have tended to retard the region's industrial diversification efforts.

These findings suggest that analysis of the relative skill intensities of civilian and defence expenditures might be a fruitful area for further research into the process of Arab industrialization.

异构数据源集成系统中能力对象集成模型及代数

异构数据源集成系统中,参与集成各数据源的查询处理能力有自身特殊的限制,导致中介器支持的查询类型变得复杂。提出一种便于异构数据源集成的公共能力对象数据模型———COIM对象模型,在此基础上,进而定义数据源能力对象代数,给出基于局部数据源的能力对象构造集成系统中介器能力对象的方法。由于可以通过计算得到中介器能力对象,用户能够提前预知中介器支持的查询类型,从而直接构造可以执行的查询,减少查询提交的盲目性;同时中介器本身也可像数据源一样参与其它中介器的集成,集成方式变得更为灵活。
