Precisely. There should be no limit to how many innocent civilians we kill. They all have flies up their noses, anyway. Eff 'em, they're not human.
Our aversion to any possibility of harming enemy "civilians" is what guarantees we cannot win.
The last war we thoroughly won, World War 2, saw us bombing entire enemy cities into rubble. We incinerated Dresden and Tokyo. We nuked Hiroshima and Nagasaki. We killed hundreds of thousands of women and children. And we did not delude ourselves that this is what we were doing.
We did what we needed to do to win.
