This isn't addressed to anyone. This is how I feel personally, having seen firsthand families suffering personal loss of family members, children, at the hands of criminals. I have family members, and friends that were actual combatants in wars ranging from WWII, to Vietnam, to Afghanistan, and Iraq. Torture, and the killing of innocents was prevalent in their worlds.
My now deceased uncle never talked about earning 7 Bronze Stars and a Purple Heart during the Philippines invasions he was on. He was almost 90 before we learned he had those medals.
What he talked about was, pows beaten and starved to the point that he would carry them like small children, two at at time to trucks and jeeps when the camps were liberated.
The Geneva Convention is a "pipe dream" created by people NOT doing the fighting to make war appear more "humane".
When the enemy hits back, you hit back harder. You punish/torture them for their resistance.
You bomb their neighborhoods and towns into powder, kill their families, but when you capture what's left, you treat them humanely , and you feel better about what? Yourself?
When I think about how I might feel if a group of foriegn men came in and destroyed my home, and killed my family, I can't imagine the rage I likely would feel. To think differently, without ever having experienced such trauma personally, is unrealistic.
