Our military is not separate from the population. They live among us. They have civilian friends. If it does come to an armed revolution much of the military would join in, others would refuse to fight and stay neutral. I think few would attack the civilian population. (My emphasis)

The military functions on orders, not emotion.

And soldiers have a duty to disobey any unlawful order. Review the Nuremburg trials if you doubt that.

[R. Scott]

… orders not, emotion.

But they are not automatons. When it comes to emotions we do our best to dehumanize our enemies. Ragheads, gooks, krauts were all terms that were used to bring emotion into our wars.
