The “CHDS/Ed” website hosts learning materials used by various Center for Homeland Defense and Security programs. One of those items is a multi-media annotated version of the 2015 Worldwide Threat Assessment. It is available at this link – https://www.chds.us/coursefiles/NS4156/WWTA_digital_publication/WWTA_2015/index.html
Here’s what CHDS/Ed says about the threat assessment:
The Worldwide Threat Assessment has been presented to Congress annually by the Director of National Intelligence; and before that office was created, it was presented by the CIA Director in his position as the Director of Central Intelligence. This annual threat assessment testimony, published as text, is one of the most informative top-level products of the U.S. Intelligence Community that is publicly available. Since 2014, the Center for Homeland Defense and Security at the Naval Postgraduate School has produced and provided a multi-media enhanced, annotated version of the text document.
