The answer lies in the heart of man - modern or ancient.
The Temple will be rebuilt and filled with the Glory of God. It is the center of the Millennial reign of Christ.
So the Dome is ultimately doomed. When and how? Stay tuned.
The presence of that awesome and transcendant Being is always present over the Temple Mount, and if you don't believe me(and have an ounce of spiritual insight) go there and pray and be convinced.
Bless the Lord our God, and may His Temple be speedily rebuilt in our days.
