But as is typical, there was significant mission creep in Afghanistan. We went from striking back against those who attacked us, to regime change, to nation-building, to policing their country for them. And we do it all now with an authorization that is flimsy at best, with the reason blurred, and the costs now known. We do it with an authorization that was debated and passed before some of our newest military personnel were out of diapers. This isn’t fair to them, to the American people, or to a rational foreign policy.

The Afghanistan war going beyond its original mission has an enormous cost. First and most important is the cost to our troops. Deaths, injuries and unnecessary deployments causing harm to families are certainly the most important reason as to why you don’t go to wars that aren’t necessary.
