Heres a very nice defense of the nominee. A taste:
Bolton -- whom Ive met but dont know well -- is blunt, which is an advantage in an institution where words are more often used to disguise meanings than to elucidate. He is unafraid of being disliked, which will be an advantage in a place where everyone will dislike him. In the past he has been unafraid of arguing his points, even in Europe, where they are deeply unpopular. Most of all, though, Bolton, who has been writing about the United Nations for decades, is one of the few people in public life willing to draw the distinction between what the United Nations actually is and what everybody would like it to be.
The trouble with many U.N. defenders is that they refuse to see this fundamental problem, and demand a constantly expanding role for the United Nations without explaining how its lack of democratic accountability is to be addressed. The trouble with many U.N. detractors, in Congress and elsewhere, is that they see the corruption and nothing else. But there is a role for U.N. institutions -- in Afghanistan, or in international health -- as long as that role is limited in time and cost. And there is a desperate need for U.N. reform. In defense of John Bolton: He may, if he can get confirmed, be one of the few U.N. ambassadors who has thought a good deal about how to set such limits and make such reforms. And if he isnt invited to a few cocktail parties along the way, at least he wont mind.
