This father is only criticizing the means--drones, bombs, or "boots on ground". Why not criticize the ends as well? Should the US be involved in any way militarily in Yemen? If American lives are not worth risking, should the lives of Yemenis also not be put in the crosshairs, whether of an M-4, F-16, or Predator Drone? May his son RIP and the US learn that the policy is also flawed, not just the process.
