That is a good summary of Theological Anti-Zionism known as Replacement.
In the new covenant the only true Zion is the heavenly one.
"22 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, 23 to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect, 24 to Jesus the Mediator of the new covenant, and to the blood of sprinkling that speaks better things than that of Abel." (Heb. 12)
Old Zion was only a type of the heavenly reality. Except for its typological teachings, old Zion no longer holds any theological significance for Christians.
