Yesterday, I noted with disgust that Iran was elected to the UN Disarmament Commission (UNDC). Having found the http://www.un.org/News/Press/docs/2006/dc3017.doc.htm relevant UN Document, I can now report that it was elected by acclamation as a Vice Chairman. Chile and Uruguay were similarly elected, and to the same position. Other members of the UNDC include South Korea (Chairman), Cuba, Guyana, Brazil, China, Belarus, New Zealand, Switzerland, Australia, Viet Nam, Japan, South Korea, Indonesia, Austria, Sierra Leone, and the United States (!).

Would someone please explain to me how the U.S. could vote in favor of Iran?

Background on the UNDC can be found here.
