Our paper investigates the political trajectories of armed actors in Mali since 2012, using recent theoretical advances on alliance formation and collapse in civil wars. Our paper establishes an analytically productive distinction between levels of wartime cleavages and factors shaping groups’ trajectories. Strategic alliances, we argue, emerge from anticipated benefits on the national political scene as well as in the local political economy. The two sets of considerations do not necessarily converge. This dual logic is studied through the cases of two armed groups, both siding with the government after originally aligning with jihadi and separatist coalitions respectively.  相似文献

In the global war against terrorism key questions need to be asked concerning how Al Qaeda is reorganizing and who will be leading it. In the absence of, at the very least adequate open source data, how can we answer these vital questions and predict the next evolution of this deadly menace? One possible solution is to study the emergence and evolution of leadership within another terrorist organization. Based on an analysis of the Provisional Irish Republican Army, it is assessed that there have been at least two and possibly three distinct generations of leadership in that group. It is important to note, however, that although these three generations have emerged sequentially, they may well all be in positions of power at the same time. These generations are designated as; early or founding leaders; follow-on and continuity leaders; and embryonic leaders. Such analysis will not tell us whom the new and emerging leaders of Al Qaeda actually are but it might help us to frame the right questions to ask our intelligence collectors.  相似文献

Using annual data collected from 1988 to 2015, this study provides evidence of a non-linear relationship between military spending, economic growth and other growth determinants for the South African economy. The empirical study is based on estimates of a logistic smooth transition regression (LSTR) model and our empirical results point to an inverted U-shaped relationship between military spending and economic growth for the data. Furthermore, our empirical results suggest that the current levels of military spending, as a component of total government expenditure, are too high in the South African economy and need to be transferred towards more productive non-military expenditure in order to improve the performance of economic growth and other growth determinants.  相似文献
