Though much progress has been made in recent decades to flesh out the rules on how we fight, much less progress has been made in answering the question, what we fight for. Liberal democracies who wage war today often fail to articulate a coherent vision of what they aim to achieve or how their interests would be satisfied through war. In other words, while the means of war have become more constrained and subject to strict regulation, the goals of war are as malleable and varied as they ever were. Exacerbating matters are substantial financial and business interests in political decision-making about armed conflicts. These observations help explain the phenomenon of ‘forever wars,’ as well as illuminate the challenges for conflict resolution.
