The Convention on the Rights of the Child has been ratified by numerous countries. Guess what country has not ratified this international human rights treaty? That's right, Somalia. Oh, yeah, and the United States of America.
I've heard the opposition to ratification is the concern that the treaty would override US law, but no such worry about, say, the Pan Pacific trade treaty.
