This combination A-Z encyclopedia and primary document collection provides an authoritative and enlightening overview of U.S. anti- and counterterrorism politics, policies, attitudes, and actions related to both foreign and domestic threats, with a special emphasis on post-9/11 events.This book provides a compelling overview of U.S. laws, policies, programs, and actions in the realms of anti- and counterterrorism, as well as comprehensive coverage of the various domestic and foreign terrorist organizations threatening America, including their leaders, ideologies, and practices. These entries are supplemented with a carefully selected collection of primary sources that track the evolution of U.S. anti- and counterterrorism policies and political debate. These documents will not only illuminate major events and turning points in America's fight against terror-both foreign and homegrown-but also help readers understand debates about the effectiveness, morality, and constitutionality of controversial policies that have either been implemented or proposed, from waterboarding to targeted assassination to indefinite incarceration at Guantánamo Bay.In addition, this resource shows how political controversies over anti- and counterterrorism strategies are spilling over into other areas of American life, from debates about privacy rights, government surveillance, and anti-Muslim actions and beliefs to arguments about whether U.S. firearms policies are a boon to terrorists.
