They won't raise the Dome- they know if they actually build on the true Temple mount they would be destroyed (again) as what happened with the Julian the Apostate "re-build". They will be happy to build their false temple on the Fort Antonia site to usher in antichrist. At least it might survive. Jesus wasn't fooling around when he said no stone would be left on the other referring to the destruction of the actual Temple ( forever)
