""Of the 91 decisions made by the United Nations body since it was created three years ago, so far, 39 have singled out Israel for criticism, while only three votes have involved Syria, and one dealt with Iran."""

If I may expand on my earlier reply, no it could not Don.
The "body" was The Human Rights Council which considers abuses within states.
