Now that’s a bow tie.
Yes, this is my look. I’ve worn a bow tie for the last 30 years. One time I went to class without it, and the students started booing, saying “Where is your bow tie?!”

Where do you teach?
I’m an adjunct professor at Georgetown, where I focus on terrorism and the proliferation of weapons of mass destruction. I also co-founded a think tank: Iran Policy Committee.

This is a pretty contentious moment for Iran.
Totally. There’s too much attention paid to either negotiations (Obama) or military strikes (Netanyahu) and not enough paid to a third option: regime change from within as a way of getting around the possibility of a nuclear-armed Iran.
