Maybe someday we will have a smart bullet that can only hit what we want it to. The thing is that we don't. When you are combating and enemy that has no problem sending a kid at you with a bomb tied to them, you have to keep watch on everybody. When Hitler invaded Europe we sent enough troops to literally walk across the continent looking for guys in Nazi uniforms and they found them all. Even the Nazis wouldn't dress like civilians or use children as bombs. If we put enough boots on the ground in Iraq or any other middle eastern country it is our casualties that will rise the fastest. Either from thinking a child is harmless, or that every civilian you pass is a true civilian and not packing an AK under their robes. At some point you have to blame an enemy that hides behind innocence or even uses it as a weapon for their own casualties. If a man with a machine gun was hiding behind an old lady shooting your friends, at some point you have to take into consideration who you should protect. You might lose 4 friends and save the old lady, then get killed yourself later without those friends to protect you. Basically war is messy, the soldiers I know all say they are there to protect each other regardless of politics. When I think of them having to deal with those type of situations, the whole drone strike thing doesn't look so bad. If the only way to save their innocent is at the loss of more of our soldiers, I personally have to say their innocent need to stop being around terrorists if they are so innocent.
