If I’m reading III.30 right, NM suggests that the virtuous man should kill his envious opponents, if need be – they should be prepared to “crush envy.” I guess I’m still at a loss to understand his definition of “virtuous.”

The argument for military organization in III.31 makes sense to me in one context: universal conscription. While I didn’t have to go through that (and thus, its easy for me to talk), it seems that this experience would tend to bind the participants together (as a common experience) and more closely to their country. Of course, its also good to create a reserve in time of war. NM is on to something here.
