I recently completed an online version of PAFF 4005 Counterterrorism in a Changing World. I designed the course around the terror attack on New York City and Washington, D.C. on September 11, 2001. I realized that many of our students were young children at the time – and indeed that is the case. The course starts with this attack but moves quickly to focus on what it has meant for the United States for our overseas counterterrorism operations. I am running the course for the first time this semester and am looking forward to see how the students react.
