Edo - The UN and the US have both said Israel should revert to 1967 pre-war borders, which includes East Jerusalem as off-limits to Israel. East Jerusalem was controlled by Jordan from 1948 - 1967.  Jordan could have created a Palestinian state any time while they occupied the land. They didn't. Before 1948 there were Jewish populations in the Old City that were kicked out by the Jordanian Army. Since 1967 there have been several wars and violent intifadas. Losing wars has consequences. Israel is not going back to the 1967 lines. Until that is understood, peace is impossible.
