Mark M. Lowenthal's trusted guide is the go-to resource for understanding how the intelligence community's history, structure, procedures, and functions affect policy decisions. In this Seventh Edition, Lowenthal examines cyber space and the issues it presents to the intelligence community such as defining cyber as a new collection discipline; the implications of the Senate Intelligence Committee's staff report on enhanced interrogation techniques; the rise of the Islamic State; and the issues surrounding the nuclear agreement with Iran. New sections have been added offering a brief summary of the major laws governing U.S. intelligence today such as domestic intelligence collection, whistleblowers vs. leakers, and the growing field of financial intelligence.
