Twenty years after 9/11, how has the terrorism landscape changed? Where are the threats to the U.S. coming from? Is New York state still a target? 

Capital Tonight spoke with professor Victor Asal, the co-director of the Project on Violent Conflict, which is affiliated with the National Consortium for the Study of Terrorism and Responses to Terrorism (START).

Asal is also director of the Center for Policy Research and a professor in the Department of Political Science at the Rockefeller College of Public Affairs and Policy. 

“Terrorism, like any other political phenomenon, goes up and down. And I think we are going in a direction where we will see more domestic terrorism from right-wing extremists and from racist extremists in America,” Asal told Capital Tonight. “In terms of protecting ourselves, we need to have more research done to identify where the threats are coming from.”

Asal said that New York City will always be a target for terrorists.
