It’s a sensitive point for many who are watching from the sidelines. Asks M.H. Ansari, a former permanent representative to the UN: "If an individual is so tainted, what signal are you sending to the world on the Palestinian question? After all, you were party to all resolutions against Israel, including the one on the Shabra and Shatila massacres?" As Israel’s defence minister in 1982, Sharon oversaw the invasion of southern Lebanon that resulted in the killing of over 2,000 Palestinians by Christian militias backed by Israel during the long night of the Lebanese civil war. The Security Council condemned it as a criminal massacre through its Resolution 521 (1982) adopted unanimously.
