Drones kill way to many innocent civilians. In fact, they probably kill more civilians than bad guys (and girls). These things are not reliable at all and they need to be banned. They are likely to fuel the fire and prevent peace. A country is less likely to offer peace when their civilians are killed by drones.
Even one civilian killed by the United States of America is to many. The Iraqi/Afghan people should not have to live in fear that they will have their faces branded with an iron from the Taliban or the fear of walking outside on a sunny day and BOOM… dust. It is unfair for them and is wrong.
