As it stands, it is very taboo for Jews to visit the Temple Mount. When Israeli Prime Minister Ariel Sharon went up there in 2000, it caused the second Intifada. Jews visiting the ruin, which houses the Dome of the Rock mosque, has been the cause of Arabs rioting in the past. And there have been halachic rulings by orthodox rabbis, forbidding Jews to visit the site. However non-Muslims, during the morning on certain days of the week can scale the bridge from the Old City and visit the other side of the Kotel – but alas are forbidden to pray.
Officially, there really is no plan set in stone for visiting there, like there is in Hebron, at the Cave of Machpelah; and such a plan would have a set time for Jewish prayers, however the Islamic Christian Society in Support of Jerusalem says that this would be unacceptable. However, they have yet to explain their reasoning.
If Israel were to give East Jerusalem to the Palestinians, Jews and probably other non-Muslims would be kissing away their dream of holding religious communion at the Temple Mount. Additionally, Christians should fear what would happen if the Church of the Holy Sepulchre became under Palestinian control. Putting the threat of violence on the State of Israel aside, religious tolerance would obviously become enforced in Jerusalem’s Old City.
In Bethlehem, during the Intifada, PLO terrorists fled to the Christian Church, which is the scene of the Nativity for Christians. They held the monks hostage, stole valuables, left feces all over, starved the Christians and all but ruined the site.
In Jerusalem, Muslims built themselves a mosque taller than the holiest Christian edifice in the city, just to undermine it. They built toilets overhanging it and they broke through a wall into a couple of storerooms of the Church, and occupied them. The PLO refused to return the rooms, until after much protest, Arafat finally gave in.
Religious Christians who would like to see Israel lose control of East Jerusalem and holy sites in the West Bank must be out of their mind, unless they are thinking of converting to Islam.
