The U.S. has denied a visa to Hamid Aboutalebi, Iran's choice as ambassador to the United Nations, which is based in New York. Aboutalebi is an experienced diplomat, but his past involvement as a translator during the 1979 takeover of the U.S. Embassy in Tehran is problematic. Iran has complained to the world body, and a special committee is set to review the issue next week. Bloomberg reporter Sangwon Yoon explains the diplomatic controversy and how it may play out.
