Christ's Commandments to Public Enemies

The word used here is exclusively enemikus, the enemy whom one can hate. You might think that this distinction would be an important exegetical matter. Yet I have been unable to find anything in the fathers of the Church on the matters of our duties with respect to public enemies. Only a little of it expands on the biblical injunctions regarding personal enemies. Shmit: Christ's commands certainly does not mean that one should love and support the enemies of one's own people.
