Five years after the 9/11 terrorist attacks, the United States and its allies hold a mixed record of achievement in executing the global war on terror. Domestic security and intelligence operations have improved, but the nature of the terrorist threat is changing dramatically, complicating efforts to secure homelands and defeat the groups and ideologies that nurture terrorist movements around the world. CSIS has undertaken a project to assess the degree to which a wide range of policies and practices enacted by government and business over the last five years have increased security and diminished the threat of terrorism in the United States. CSIS experts identify both significant accomplishments and continuing challenges in the U.S. conduct of the global war on terrorism in six critical areas: The Evolving Threat of Terrorism Ideology and the Battle of Ideas; America's Domestic Security; Intelligence International Cooperation; U.S. Strategy and Capabilities for Winning the Long War.http://www.csis.org/media/csis/pubs/five_years_after_9-11smallsize.pdf
