Agreed. The deal that will stick for a short time would include the Temple I believe and may not come until after a short war where Israel will eliminate a lot of the opposition.
The Third Temple certainly must be up and operating before the mid-point of the Tribulation.
That way the Antichrist will be able to halt the daily sacrifice and oblation. Declaring himself to be “God”.
Wow, what a freaky time that will be for the inhabitants of planet Earth. /understatement
