"In this age, I don't care how tactically or operationally brilliant you are, if you cannot create harmony-even vicious harmony-on the battlefield based on trust across service lines, across coalition and national lines, and across civilian/military lines, you need to go home, because your leadership is obsolete. We have got to have officers who can create harmony across all those lines."
