In Can Intervention Work? Gerald Knaus and Rory Stewart use Afghanistan and the Balkans to test different theories of intervention. They write in the belief that "policy makers are not condemned to stumble on in darkness, overly cautious at one and overly confident at another relying on luck to make up for the incapacity to control events and on ideology for the inability to understand them." In their discussion of Afghanistan and the Balkans, do you find their arguments and their conclusions convincing? Use Kinzer and class materials as well in tackling this question.
