Foreign policy is an explicitly amoral enterprise.

From Richard Holbrooke - and I miss him every day - I learned two things. One, prioritization: Never take your eye off the longer-term reforms. The other thing is, he was a hell of a schmoozer! So I should take advantage of my Irish love of beer and gift of the gab, and build relationships. That's a cherished part of the job, asking someone, "How did you get to be the Rwandan ambassador?"
