All Political bullshit aside, that shit is fucking wrong. Pissing on someone after you have killed them shows what character, ethics and morals you have. IMO justifying it because "one of them beheaded a solider once" or whatever shows your intelligence level.
Conducting yourself regardless of war or culture in this manor is deplorable i don't give a fuck where you come from. Its not ok to act like a fucking disrespectful cretin because someone else is doing it. Want the world to be a little bit better of a place? then don't piss on them after you invade them and kill them. (could care less if you think we need to be there or not, its not my point. we showed up on their spot and we kill people. you can argue if its warranted or not all day but it does not negate my point)
I feel sorry for the rest of the armed forces who have to be associated with those worthless assholes.
The ignorance in this thread saddens me although its not very surprising.
