WASHINGTON, D.C. – John Bolton’s resignation today as the US Ambassador to the United Nations is a positive development for the United States. Mr. Bolton was a diplomat who lacked diplomacy. His antagonistic ways tarnished the United States’ relationships at the UN and denied him the political support in Washington he would have needed to keep the job. President Bush now has an opportunity to nominate an ambassador committed to reform of the institution in a positive way and who understands why the UN matters and how it can advance the national security goals of the United States.
