It will be finished 1260 days after the Antichrist signs or "confirms" a 7-year peace deal with Israel, at which point the Man of Perdition defiles the 3rd Temple, probably during its dedication week which I surmise will coincide with Passover. Trump is not the Antichrist, but his brokering of deals between Israel and the Arabian peninsula nations sets the stage for them (Sheba and Dedan), along with the West (Merchants of Tarshish and the young lions thereof) to protest the Russia/Iran/Turkey (Gog, Magog, Togarmah, Persia, etc.) invasion of Israel. All that's left is the "hook in the jaw" of Russia and her allies which I believe is the Rapture. The Rapture incapacitates, at least temporarily and maybe permanently, the US and Nato, leaving Israel vulnerable to a coordinated, massive invasion.
