I understand that but perhaps the problem is that we have too many people willing to kill someone else just because someone told them to. I can't understand how people can blindly follow orders to kill. I would tell Obama you wanna that person killed go ahead and do it yourself.
The only time I would join the military it was if another country was invading mine. I would never accept to be the invading force, not matter what banner they choose to fly to justify it.
