This problem arises in most non-technical meetings aiming to articulate new policies in response to pressing issues where experts are themselves in disagreement. Its importance has been frequently noted in the debates of the General Assembly of the United Nations and in the conferences of its Specialized Agencies.The permanent members of the UN Security Council met five times in the 1991-92 period to discuss arms restraint. Together they collectively account for 90% of weapons sold worldwide. They have only be able to agree on vague guidelines for arms sales and standards that each says it already meets.
