New Dean of Columbia's School of International and Public Affairs:

If you want to be dean of Columbia's SIPA, you should

(a) invite Iranian president Mahmoud Ahmadinejad to campus and announce that you would "certainly" have invited Adolf Hitler as well, resulting in a public relations debacle for your university;

(b) sign a petition calling for divestment from Israel.

(c) apologize for a high-level Communist Cuban official who served with Castro since before the revolution by drolly noting noting that "many decent and honorable people in Cuba are Communists. They work in government agencies, schools, laboratories, and clinics to improve the lives of their fellow citizens." UPDATE: And with regard to the official's political perspective, state, "I respect his convictions."

(d) all of the above.

Answer: (d), of course.
