On November 28, 2016, Abdul Razak Ali Artan, an 18-year-old legal resident of the United States whose family was originally from Somalia, used a car to mow down a group of people at the Ohio State University.

Stateless people are hidden. During the 2011 refugee crises, it was obvious that people were fleeing Somalia and Libya - there was a lot of international attention. Statelessness goes undetected because stateless people are in legal limbo and are afraid to show up.

When I was commander of Central Command, obviously we were very concerned about the developments in Yemen, the developments in Somalia and elsewhere, in Africa and so forth. But the al Qaeda senior leadership is under unprecedented pressure.

My mother was an activist; so was my father. They came from a generation of young Somalis who were actively involved in getting independence for Somalia in 1960.

The house I was born in in Somalia was right next to a big market. A lot of beggars or panhandlers would be in front of our house constantly, and my grandfather and grandmother would always invite them in to have food with us and have them take whatever was left over.

The most memorable interviews for me are folks whose names I don't know: young civil rights leaders in the South, showing great courage as they walked into a town in the dark of night. A doctor working for 'Doctors Without Borders' in Somalia, operating by kerosene light in a tent. Those are the kinds of people that linger in your memory.

The main thing that gives me hope is the media. We have radio TV magazines and books so we have the possibility of learning from societies that are remote from us like Somalia. We turn on the TV and see what blew up in Iraq or we see conditions in Afghanistan.
