Obviously, you have never been in combat. You have no idea what our kind go through do you? It's easy for you to demand an apology for something you do not understand.
We are at WAR. And when we fight wars, there will be unfortunate incidents like this. There always has been and there always be. WAR IS HELL! There is no other way to put it.
If you had even the slightest insight into what happened during World War 1, 2, Korea, Viet Nam, etc, we would still be only halfway through the list of apologies due from World War 1.
The soldier snapped, as they often do in combat. I have seen it first hand myself. His actions were not ordered by his commanders, or the CIC, so there was little anyone could do to prevent it. Is it a tragedy? Absolutely! Should the USA apologize for the inevitability of what war creates? Absolutely NOT! The country being liberated is and has benefited from thousands of our people dying for their cause. There is no other payment required!
