The nations whose leaders make such comments, and the only criticism is that they should have said it quietly instead of yelled. I know some people from those countries, and in general, as individuals they are good people. But they are far more silent than those who disagree with our government: I see no vigerous discussion of "impeaching Ahmadinejad" or cracking down on the Muslim Brotherhood.
Iran and Korea come to mind. And there are other places where I could not go without risking my life just being there, for the reasons stated above. Places that support terrorists who push old men in wheelchairs off of cruise ships, and blow up children's birthday parties knowing there are only innocent civilians present.
