They might want to rebuild the temple, but the muslims mae it into a mosque and they'd need to take the gold minarent off it and muslims would be mad, it's the 3rd most important site in islam. Also, there's a prophecy that jesus will come back when the temple is rebuild, and when that doesn't happen, christian evangelicals would be dismayed and they would support israel less, allowing the muslims to overrun it. So I think jews are happy to just have the land and status quo.
