In this debate, success or failure has usually been judged based on whether the state subjected to economic isolation surrenders without being defeated on the battlefield. This approach, however, has missed a more important way in which economic isolation affects its target: strategy. Economic isolation constrains a state’s strategic choices and leaves its leaders to choose from the remaining options, which are almost always riskier. As analyses of German decision-making in World Wars I and II demonstrate, these riskier strategies often involve escalating the conflict at hand. ow does a state’s access to the inter- region at the start of a conflict.2 On the other hand, national economy affect its strategy not all potential U.S. adversaries are so well con- to prevail in war?
