Indications from 2Thessalonians 2:1-4 are that Jesus will not return until the antichrist (i.e. “man of sin”) is revealed and takes his seat in the temple, proclaiming himself to be God.
Presently that really cannot happen in any literal sense, since there is no temple. However there is definitely interest that is building on the part of Jewish Israelis to erect a temple on the original site of Solomon’s and Ezra’s (i.e. Herod’s) temples. That site is now occupied by the Al Aqsa mosque. Apparently when Jerusalem was recaptured in 1967 by Israel, there was some sort of “deal” made whereby non-Muslims can visit the site, but cannot pray there. Increasingly, Israel is chafing against this “deal” and is desirous of erecting a temple, perhaps on this site.

Thy kingdom come!
An ultimatum should be issued by Israel. One more life lost, one more threat, and we will tear down this temple to the false god. They can’t resist, and will make it happen. Option 2 would be to just tunnel under it and build the temple underground.
