President Bush has nominated John Bolton to become the next ambassador to the United Nations. Bolton most recently served as undersecretary of state for arms control. Secretary of State Condoleeza Rice made the announcement Monday. “The President and I have asked John to do this work because he knows how to get things done,” Rice said. “He is a tough-minded diplomat, he has a strong record of success, and he has a proven track record of effective multi-lateralism.”
