I'm a bit confused, because as far as I can tell, those soldiers didn't do anything to that dog. They were just making fun of it. Sure, that's disgusting in itself, but I didn't see what I thought I was going to see.
And besides, this is a country that's been at war for years now. Soldiers that are there for any length of time are going to be different than before they first got there.
Not defending their behaviour, just examining it. Anyone who knows me knows how much I like to bash anything Iraq war related.
