If American troops are being ambushed by the Taliban, air strikes can't be used if there is civilians in the area. This is the Obama message of you're on your own if you need help being sent to our military. This is also a message being sent to the Taliban that if you want to defeat the Americans use civilian shields. You can't win a war when your opponent has the ability to do whatever they want and you are severely restricted in everything you do. If this is the way we are expecting to fight a war we should bring our troops home now instead of sending them on a suicide mission. Barack Obama should be impeached for being a traitor.
