Generally the "follow the leader" game at the United Nations revolves around condemning Israel for its very existence. Yesterday, in a rare display of morality a number of countries marched out of the General Assembly when Iran's Mahmoud Ahmadinejad started belittling the seriousness, the tragedy of the Holocaust.
Following is the list of countries that walked out, which Elder of Ziyon has compiled:
Canada (boycotted the speech)
Israel (boycotted the speech)
