Now, how about some report extracts on Israel's doings dduring the same period.

NOTE:

"UN Watch" is a Geneva-based organization closely associated with rightist sectors in the United States and Israel that claims to monitor compliance of the United Nations with its charter. According to its website, UN Watch "serves as the central forum for discussing international economic and social issues, and for formulating policy recommendations addressed to Member States and the United Nations system."[1]

Despite efforts to paint itself as an independent watchdog group, UN Watch has repeatedly been accused of having a staunchly "pro-Israel" bias and on outlook on Middle East peace that is closely in line with that of Israel's right-wing Likud Party. For many years, the group was funded by the American Jewish Committee (AJC)—publisher of the neoconservative flagship journal Commentary, whose editors have included Norman Podhoretz and Irving Kristol—which has made use of its offices in Geneva, as well as those of other affiliated groups, including the Transatlantic Institute in Brussels.[2]
