IMO, things appear to be almost weird enough but too quiet for the rebuilding. Maybe we should stop being chickens and pray for idiots everywhere to be motivated to start the shindig (Yechezkel).
The State of Israel government is embarrassed by religious fundamentalists such as might be serious about a rebuilt Temple, and would never allow it.
Any serious attempt would be under the authority of the Ashkenazi and Sefardi Councils of Torah Sages, which the Temple Institute is not.
Christians and other outsiders wildly underestimate the difficulties, even if there were no Muslim threat.
