In 1991, the U. N. Security Council, through Resolutions 686 and 687, demanded that Iraq return all prisoners from Kuwait and other lands. Iraq's regime agreed. It broke its promise. Last year the Secretary General's high-level coordinator for this issue reported that Kuwait, Saudi, Indian, Syrian, Lebanese, Iranian, Egyptian, Bahraini, and Omani nationals remain unaccounted for -- more than 600 people. One American pilot is among them.
