A simmering dispute between Washington and MANILA erupted again when U.S. Ambassador Nicholas Platt assailed a speech by Philippine Foreign Secretary Raul Manglapus. The Manila official had called America the "constable of the world" and questioned whether "that responsibility is . . . just." In MALAYSIA, more than 2,500 demonstrators rallied to support Saddam Hussein. Another 2,500 have volunteered to fight with Iraq or carry out medical or other relief work, the opposition party said.
