Secretary of State Hillary Rodham Clinton pledged a new American openness to ideas from abroad, especially the Muslim world, during a visit Wednesday to Indonesia. Anti-US protests were held in several cities, with some Islamic hard-liners setting tires on fire and others throwing shoes at caricatures of Clinton, but the rallies were small and scattered. Indonesia, the world's most populous Muslim nation, is the second stop in Clinton's inaugural overseas trip as the top US diplomat. She said that was "no accident," with the trip designed to show support for the country's hard-won democracy as well as its efforts to fight terrorism while respecting human rights. Steps were already being taken to improve relations, she said, announcing at a joint press conference with Foreign Minister Hassan Wirajuda that Peace Corps operations were expected to resume here after a long absence.
