The Art of Tetman Callis

“The history of diplomacy is the history of relations among rival powers, which did not enjoy political intimacy, and did not respond to appeals to common purposes.  Nevertheless, there have been settlements.  Some of them did not last very long.  Some of them did.  For a diplomat to think that rival and unfriendly powers cannot be brought to a settlement is to forget what diplomacy is all about.  There would be little for diplomats to do if the world consisted of partners, enjoying political intimacy, and responding to common appeals.” — Lippmann, The Cold War
