FLYNT LEVERETT, former assistant to Secretaries of State Colin Powell and Condoleezza Rice, verified the 2003 "serious proposal" from Tehran for a comprehensive agenda for US-Iranian rapprochement. Last week Rice faulted him for not telling her about this communique, "I don't know what he's talking about.", she said. Leverette is confident that Powell and Rice had seen it. Yesterday he accused Rice of "misleading Congress and the American people on this issue."
