Maranatha, Jesus!!!
It also makes perfect sense as a way for peaceable resolution of a thorny problem the rebuilding of the Third Temple. The only problem I see with this proposal is that both sides must want a peaceful solution. Somehow or other, I feel fairly sure that Islam will not allow its Holy Place to be "defiled" by the presence of a Jewish Temple right next door to the Dome of the Rock, wall or no wall.
Allah is not looking for peace. He's looking for the universal submission of all mankind to himself. Or so it seems to me, FWIW.
Thanks again, dearest sister, for the excellent link!
