The war in Afghanistan was one of the most brutal and long lasting conflicts of the second half of the twentieth century. Anthropologists specializing in Afghanistan who wrote about the war at the time reiterated the United State's Cold War rhetoric rather than provide objective analyses. Others ignored the war altogether. What happened in Afghanistan, and why, and the need for objective reassessments only came to mind after the September 11th attacks. This paper examines the genesis and various permutations of the Afghan war in terms of causal dynamics embedded in the broader interstate relations of the world system and its competing military complexes during the second half of the twentieth century and changes in that system in the post-Cold War period.
