Some countries have atrocious human rights records.
The U.S. is involved with this world court that could possibly see U.S. Citizens tried for offenses contrary to the U.N. mission statement. I for one do not want our soldiers overseas handed over to anyone. They will not be satisfied until the might of The United States is subserviant to their needs and goals. While I question some of our involvement in the United Nations, our response to being voted off the Human Rights Commission is akin to the eight year-old taking his ball away because the ball isn't passed to him enough. We are quick to condemn those who don't do things as we like.
