The State Department said Thursday it was studying the imposition of additional sanctions against North Korea for its October 9 nuclear test. Secretary of State Condoleezza Rice had said Wednesday that the United States "is now obligated by law to adopt additional sanctions on North Korea under national legislation." She mentioned the so-called Glenn Amendment, which bans US assistance to non-nuclear weapon states found to have exploded a nuclear device. In 1998, former President Bill Clinton invoked such sanctions against India and Pakistan after the rivals tested nuclear weapons.
