I too am appalled. But the question remains, what should we do?
As am I and with the same question. During WW2, we were at war with the power responsible for the concentration camps and liberated a number of them. I am not sure if the military situation at the time would have allowed us to do a whole lot differently than we did. Now the lunatic with the camps has the ability to start a nuclear war, so we are supposed to do exactly what?
