This compelling presentation will discuss how 9/11 went from an aspiration to a reality, and to where the threat environment has traveled to 20 years later. It will start with the planning, execution, impact, and how we responded to 9/11 from both public and private sector perspectives. It will end with where we are today and how we should respond from a public and private sector standpoint. The backstory is about the need for financing to carry out acts of terrorism and how public and private partnerships can identify and disrupt the flow of funds necessary to sustain terrorist activities.
