It's probably not the dog's fault. Another dog, perhaps one of its leaders like Yasser Arafat or Osama bin Laden, almost certainly infected it. It may look like a teenage Palestinian boy-- or today, even a teenage Palestinian girl. But that's your child it's menacing.
You can't negotiate with it. You can't reason with it. You can't talk it out of tearing your child's throat out and ripping her limbs off, as often happens when it uses a bomb. There is only one thing to do that's safe for your child, and it's probably the most humane thing for the dog as well. If you're part of civilized humanity, it's not only your right but also your responsibility to do it.
