Where's PETA in Iraq?

I like the Tom Ricks blog, it's just enough contact with military matters for someone who describes himself as a natural-born civilian. This post reveals a disastrous situation in Iraq, where our esteemed soldiers are killing dogs, then carrying over the habit to Afghanistan.  (I don't remember Vietnamese being fond of dogs, and I won't try the obvious joke.) Unfortunately, despite the fact our military is composed of great people, you put a weapon in someone's hands and you create a situation where the person can abuse the power.
