Clinton Pledges Bigger Role For Besieged State Department.

Mrs. Clinton, in presenting a two-year review that has been one of her signature projects, declared that ''leading through civilian power saves lives and money.'' Among key changes is a heavier emphasis on resolving conflicts and a pledge to reinvigorate the United States Agency for International Development. [ABSTRACT FROM AUTHOR]
