Richard Holbrooke, a former U.S. ambassador and one of the most influential American diplomats of the past four decades, has died at age 69 after surgery to repair a torn aorta, reports Bloomberg news. Although Holbrooke is best known as a mediator during the war in Bosnia and in U.S. relations with China, Afghanistan and Pakistan, he was also a staunch AIDS advocate. According to a PBS interview, he helped redefine the pandemic in terms of world security, and arranged a groundbreaking U.N. Security Council Session on the topic in 2000. He chaired the Global Business Coalition on HIV/AIDS, Tuberculosis and Malaria and proposed an aggressive system of HIV testing and treatment.
