The UN General Assembly was never intended as a moral endorsement of those who attend. Having spent two years representing Israel at the United Nations, I have no illusions about the institution's shortcomings. Dictators and military rulers responsible for crushing political dissent routinely address the General Assembly without serious objection from City Hall. Once local politicians begin deciding which foreign leaders deserve diplomatic access and which do not, the city risks undermining the neutrality that has made it the world's diplomatic capital.
