“War is In no way a relationship of man with man but a relationship between States, in which individuals are enemies only by accident; not as men, nor even as citizens, but as soldiers . . . since the object of war is to destroy the enemy State, it is legitimate to kill the latter’s defenders as long as they carry arms; but as soon as they lay them down and surrender, they cease to be enemies or agents of the enemy, and they again become mere men and it is not longer legitimate to take their lives" - Jean Jacques Rousseau

Do you think this is still applicable today? Who are the “defenders” he mentions?
