UNITED NATIONS (Reuters) - U.S. ambassador to the United Nations Nikki Haley said on Friday that U.S. sanctions against Venezuela were a strong message to President Nicolas Maduro that the United States would not tolerate a “dictatorship” in that country.  Haley, speaking at United Nations headquarters in New York, said she had not been asked to meet at the UN with visiting Venezuelan foreign minister Jorge Arreaza.
