There must be a joke in this since John Kerry is the first Secretary of State since Hillary Clinton. But anyway she did a great job and used all of her skills and interpersonal ways of relating to people around the world. John Kerry is who he is, rather pedantic and dependable but not great.
No, John Kerry will not go down as the best secretary of state since Hillary Clinto due to the fact that he has served during one of the worst times in American History for Government approval. With Congress having an approval rate of 5%, and the White House's hovering only a bit above that, to think he will be remembered fondly is asinine.
