The Christian endgame (if you give Revelations credence as a predictive text bestowed by God) hinges on conditions being "right" for the return of Jesus, the final battle with the forces of evil, and the birth of a new Jerusalem in the Kingdom of Heaven.
Jews being in charge of "The Holy Land" is part of this thinking that the Apocalypse can be created under the right circumstances, or at the very least everything will be set and ready to go when Jesus decides to roll up again. The trying to breed a red heifer is another example of trying to manufacture one of these "signs".
If it doesn't make sense, it's because it doesn't. So much of it relies on taking Revelations seriously, either literally or as some kind of Dan Brown-esque treasure hunt of symbols and portents.
