There is a hidden country within the United States. It was formed from the astonishing number of secrets held by the government and the growing ranks of secret-keepers given charge over them. The government secrecy industry speaks in a private language of codes and acronyms, and follows an arcane set of rules and customs designed to perpetuate itself, repel penetration, and deflect oversight. It justifies itself with the assertion that the American values worth preserving are often best sustained by subterfuge and deception.

There are indications that this deep state is crumbling. Necessary secrets are often impossible to keep, while frivolous secrets are kept forever. The entire system has fallen prey to political manipulation, with leaks carefully timed to advance agendas, and over-classification given to indefensible government activities.

Deep State, written by two of the country's most respected national security journalists, disassembles the secrecy apparatus of the United States and examines real-world trends that ought to trouble everyone from the most aggressive hawk to the fiercest civil libertarian. The book:

- Provides the fullest account to date of the National Security Agency's controversial surveillance program first spun up in the dark days after 9/11.

- Examines President Obama's attempt to reconcile his instincts as a liberal with the realities of executive power, and his use of the state secrets doctrine.

- Exposes how the public's ubiquitous access to information has been the secrecy industry's toughest opponent to date, and provides a full account of how WikiLeaks and other "sunlight" organizations are changing the government's approach to handling sensitive information, for better and worse.

- Explains how the increased exposure of secrets affects everything from Congressional budgets to Area 51, from SEAL Team Six and Delta Force to the FBI, CIA, and NSA.

- Assesses whether the formal and informal mechanisms put in place to protect citizens from abuses by the American deep state work, and how they might be reformed.

Deep State is based on the authors' insatiable curiosity for the ground truth and layered on a foundation of original and historical research as well as unprecedented access to lawmakers, intelligence agency heads, White House officials, and secret program managers. It draws on thousands of recently declassified documents and candid interviews with more than 100 military, industry, and government officials.
