Letter of resignation submitted to Secretary of State Colin L. Powell by U.S. diplomat John Brady Kiesling, a career diplomat who has served the United States at embassies from Israel to Morocco to Armenia. My favorite part: “Why does our President condone the swaggering and contemptuous approach to our friends and allies this Administration is fostering, including among its most senior officials. Has “oderint dum metuant” really become our motto?”
