Sept. 19 @ 6 pm - Baker Center's Global Security Group presents Ambassador Linton Brooks on "21st Century Nuclear Challenges." Despite the nuclear programs of rogue states Iran and North Korea, the threat of nuclear terrorism, increasing numbers of nuclear weapons in volatile or fragile parts of the world like Pakistan, or the nuclear disaster in Japan - the nuclear security agenda has receded in the national debate. Global stockpiles of nuclear weapons, vulnerable nuclear material worldwide, and the byproducts of nuclear energy production will remain among the central challenges to US national security and global stability throughout the 21st century. Ambassador Brooks has over five decades of experience in national security, much of it associated with nuclear policy. While he currently is a senior advisor at the Center for Strategic and International Studies and a distinguished research fellow at the National Defense University, he previously served as the administrator of the US Department of Energy's National Nuclear Security Administration and chief negotiator of the first Strategic Arms Reduction Treaty, as well as in other key US government positions. Prior to his government service, he was a career Navy officer deployed on four nuclear- equipped ships. This event is also sponsored by the Hudson Institute, Partnership for a Secure America, and the Stanley Foundation.
