Another fact that is generally completely omitted is that best, soldiers defend against other soldiers (and in practice, they kill a lot of civilians because war is tough), so in a way those people justifying war machineries in other countries are not the excuse, they are the counterparts. It's an axis of sociopaths and conformists against humans, and this rift goes through all nations, even some families. The root causes for these rationalizations matter, not so much the rationalizations, those always shift. A child kicking a dog and Abu Ghraib differ in scale but not principle, as does looking on to either. Those onlookers love to use "we", but there is no "we" here, speak strictly for yourself.
