I still definitely think it is right up there with MIT and Columbia if you want to do Security Studies. I dont think many places offer a better committee than Mearsheimer, Pape, and Staniland (plus other people at the Harris school like bdm)
The reason I post this as an undergrad is that I'm just worried about the future of the department going forward. I want to see it continue being the place people go to to study security both at a grad and undergrad level because it is the best. Chicago used to be poli sci and I want it to get back to that.
