Paul Wolfowitz, the former World Bank president and former deputy secretary of defense who was instrumental in the US decision to invade Iraq in 2003, has been named chairman of a panel that advises the State Department on arms-control issues. Wolfowitz, now a visiting scholar at the American Enterprise Institute in Washington, will head Secretary of State Condoleezza Rice’s International Security Advisory Board, the State Department said yesterday in a statement. “The ISAB provides the Department of State with a source of independent insight, advice, and innovation on all aspects of arms control, disarmament, nonproliferation, political-military issues, and international security and related aspects of public diplomacy,” the State Department said.
