EUA: The terrorist threat to the US homeland (NIE)

National Intelligence Estimates (NIEs) are the Intelligence Community’s (IC) most authoritative written judgments on national security issues and designed to help US civilian and military leaders develop policies to protect US national security interests. NIEs usually provide information on the current state of play but are primarily “estimative”—that is, they make judgments about the likely course of future events and identify the implications for US policy.
