May be if some power-tripping, aggressive yet clueless leader didn't invade that country in the first place for BS reasons, neither those understandably frustrated, bored, worried, tired troops wouldn't even be there...may the dog wouldn't be handicapped and living a healthy life or may be he would have been hit by a drunk Iraqi driver and get killed. May be the dog was already jacked up like that years before the war?

One thing you guys are not used to in the US is the 'street dog' concept. You will hardly ever (if at all) see a street dog in a city or suburbans areas in US. People own and nurture the pets even better than their own kids.
Over there, it is pretty much the exact opposite...dogs roam the streets and only a few are ever 'owned'. They are mostly treated like sh_t, hence the dogs over there being either too aggressiveness or too scared.
When I see the pics of little kids who lost a limb due to that war, I really can not be that concerned about animals...though it is still a sad thing nevertheless.
