mr. mueller: it has to be done by a nonstate actor. if it is done by the state, we do not call it terrorism, there's a debate. like hiroshima has never influence opinion politically, but it was part of a war done by state, so usually not considered terrorism. you could call that terrorism. i want to ask a question, which i raised when we did the event going for terror and money, and this goes off of what rosa brooks said. the question is, who really believes the government should be risk neutral? i do not think that is actually true. many people outside economics department and quarters of office of management and budget are in disagreement in this country about political parties and ideologies, disagreements about what risks to confront. government, socially, what risks to leave people in markets to do with. can you speak to the utilitarian purposes that are underlying the analysis here? thanks. i accept that politicians are not going to be risk neutral. the agencies and those advising politicians should we doing risk-neutral analyses
