Europe's new subregionalism

From the Barents and the Baltic Sea in the north, through Central Europe and the Balkans, to the Black Sea in the south a range of new subregional groups and cooperation processes have emerged in Europe during the 1990s. Compared to NATO and the European Union, these new subregional groups have received little attention. Their ‘indirect approach’ to security, however, plays an important role in overcoming the legacy of the Cold War, reducing the risks of military conflict and addressing non‐military security challenges. As NATO and the EU expand eastwards, subregionalism is assuming growing importance as a means of avoiding new ‘dividing lines’ in Europe. After the wars in Bosnia and Kosovo, subregionalism is also gaining importance as a means of building cooperation in South‐Eastern Europe. The challenge for the future is to give more substance and depth to Europe's new subregional cooperation frameworks.     

Plague and Paradox: Militias in Iraq

Politicians, political pundits, and others focus a lot of attention on the political militias in Iraq, usually blaming them for their destabilising effect on the country and insisting that they disband. This study examines the impact that the militias in Iraq have on the Iraqi government's ability to consolidate control over its territory by first explaining how militias rose to prominence in Iraq during the power vacuum created by Saddam Hussein's ousting, then analysing the many ways militias adversely impact the security situation. The study then examines the other side of the argument – that is, why militias enjoy so much support in Iraq among their constituencies, and why they may actually be necessary to achieve stability in Iraq in the short term.     

A robust sensor covering and communication problem

We consider the problem of placing sensors across some area of interest. The sensors must be placed so that they cover a fixed set of targets in the region, and should be deployed in a manner that allows sensors to communicate with one another. In particular, there exists a measure of communication effectiveness for each sensor pair, which is determined by a concave function of distance between the sensors. Complicating the sensor location problem are uncertainties related to sensor placement, for example, as caused by drifting due to air or water currents to which the sensors may be subjected. Our problem thus seeks to maximize a metric regarding intrasensor communication effectiveness, subject to the condition that all targets must be covered by some sensor, where sensor drift occurs according to a robust (worst‐case) mechanism. We formulate an approximation approach and develop a cutting‐plane algorithm to solve this problem, comparing the effectiveness of two different classes of inequalities. © 2015 Wiley Periodicals, Inc.

Birth of the Cold War: irregular warfare first blood in Greece

ABSTRACT

While often held up as a model of successful American counterinsurgency, the Greek Civil War presents a unique case. Peculiar local conditions and geopolitics contributed to the defeat of communist forces in Greece. A firm British and later American commitment to combating communism stood in contrast to ambiguous support from the Soviet Union in an area they considered outside of their sphere of influence. Strong nationalist feeling among the Greek population buttressed support for the government and undermined the ‘internationalist’ concessions of communist forces. These characteristics make the extrapolation of broader lessons focused on victory through the application of overwhelming American resources and the financing of local forces problematic. If lessons are to be gleaned from this case, they should focus on the critical roles played by internal political dynamics and geopolitics in undermining the strength of the insurgent forces and how these provided a stable platform from which the counterinsurgents could operate.
