What is the primary function of the Central Intelligence Agency?

Answer 1

The CIA has three major tasks: 1. to coordinate the information gathering activities of all State, Defense, and other federal agencies involved in the areas of foreign affairs and national defense. 2. to analyze and evaluate all data collected by those agencies, and 3. to brief the President and the National Security Council- that is, to keep them fully informed of all that intelligence.

Answer 2

According to the mission statement on their website:

"The Central Intelligence Agency (CIA) is an independent US Government agency responsible for providing national security intelligence to senior US policymakers."

This can therefore be considered a summary of their primary function.
