President Donald Trump announced that he is allowing the military to decide how to proceed in Afghanistan, including setting troop levels. Though I am convinced the President is trying to do what is best for the country (who better than the military leadership to determine what they need to succeed?), military power is a tool, a means among many different tools of national power, not a strategy in and of itself. Elevating military objectives over the assessment of the politically acceptable magnitude of effort for a given strategic political goal can be a slippery slope. The literature about escalation is filled with examples of cognitive biases that encourage leaders to continue throwing good money after bad.
