Intelligence agency
government agency responsible for the collection, analysis or exploitation of information and intelligence

An intelligence agency is a government agency responsible for the collection, analysis, and exploitation of information in support of law enforcement, national security, military, public safety, and foreign policy objectives.
Means of information gathering are both overt and covert and may include espionage, communication interception, cryptanalysis, cooperation with other institutions, and evaluation of public sources. The assembly and propagation of this information is known as intelligence analysis or intelligence assessment.
Objectives
Intelligence agencies can provide the following services for their national governments.
Give early warning of impending crisis;
Serve national and international crisis management by helping to discern the intentions of current or potential opponents;
Inform national defense planning and military operations, known as military intelligence;
Protect sensitive information secrets, both of their own sources and activities, and those of other state agencies;
Covertly influence the outcome of events in favor of national interests, or influence international security; and
Defense against the efforts of other national intelligence agencies, known as counterintelligence.
There is a distinction between "security intelligence" and "foreign intelligence". Security intelligence pertains to domestic security and related threats, including terrorism and espionage. Foreign intelligence involves information collection relating to the political, or economic activities of foreign states.
Some agencies have been involved in assassination, arms trafficking, coups d'état, and the placement of misinformation propaganda and other covert and clandestine operations to support their own or their governments' interests.

Begin with the source’s own compact description: “Intelligence agency” is government agency responsible for the collection, analysis or exploitation of information and intelligence. The dossier treats that line as a proposition to test through Intelligence, agency and government, not as a finished interpretation.
Why this record matters
The phrase “government agency responsible for the collection, analysis or exploitation of information and intelligence” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Jun 25, 2026. The linked authority identifier is Q47913. The Library of Congress control number is sh85067175. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
