The United Nations has an extreme anti-Israel bias. The anti-Israel stance of the UN is a consequence of its membership structure. Twenty-one members of the UN are Arab countries, and 52 members represent Islamic countries. The Arab-Israeli conflict is essentially a religious conflict. Israel as the only Jewish state has no chance for a fair hearing in the UN.
Israel is the only democratic country in the Middle East. In contrast, the majority of Islamic countries do not have democratic regimes, and many transgress the fundamental human rights of their populations. Despite this great gap, the UN passes resolutions mostly and specifically against Israel. See the Database of UN Resolutions at UN Watch.
Quote from Move America Forward: "Instead of serving as a rallying point for free nations and free people to unite to combat terrorism, the United Nations has become a safe harbor, apologist and defender of terrorist organizations and their agents."
