When I can't wrap my head around a tough concept I often reiterate, complete with international hand signal for little, "I have a little brain." War is one of those events I will never understand. Oh I realize conflicts abound. I've had a few life changing ones in my lifetime. Tough and painful.
The bottom line is killing and torture don't cut it. So many people on and off the battle fields are affected in negative ways. It makes me sad.
