I wont get into all the preterist debate stuff. I will say that
Daniel 9:27 speaks of a covenant that is for one week (week of years = 7 years). It says the AC will confirm that covenant. It then references that in the midst of the week he causes the sacrifices and oblations to cease, inferring that the covenant is related to the rebuilt Temple and the return of animal sacrifices in Jerusalem.
The Jews are already prepared to rebuild it. Check out
www.thetempleinstitute.com they have everything ready, even prefabricating the Temple so they can quickly construct it. Priests are trained and ready for sacrifices and Temple worship.
If a peace treaty could be signed between Israel and the Palestinians and have decisions contained within related to sharing the Temple Mount and allowing Israel to build a Temple, that would be a significant prophetic fulfillment. Anyone negotiating with Israel and the Palestinians will have to address this issue. The AC will be the one who does it.
