This chapter reviews the member organizations of the United States Intelligence Community, the strategic environment that has informed intelligence and accountability in the United States, including scandals as a key driver of innovation, and the current and future threat environment as seen by the United States. The chapter examines the US intelligence accountability architecture: the House of Representative Permanent Select Committee on Intelligence, the Senate Select Committee on Intelligence, the Foreign Intelligence Surveillance Court, the Inspectors General, the Government Accountability Office, the Privacy and Civil Liberties Oversight Office, and the President’s Intelligence Advisory Board. The sheer number and complexity of accountability bodies in the US gives rise to inefficiencies, ineffectiveness, and duplication. The accountability system is replete with gaps and vulnerabilities: partisanship, collective-action problems, resource allocation, and inconsistent quality of review in congressional accountability; GAO’s limited authority to review the USIC and sensitive operations; the adequacy of the FISA court in adequately protecting the rights of Americans; and Presidential discretion in appointing and removing IGs. These issues have implications not just for the United States, but for allies, partners as well as regional and global stability.
